VMADM(1m)VMADM(1m)NAMEvmadm-- Manage SmartOS virtual machines
SYNOPSIS
/usr/vm/sbin/vmadm <command> [-d] [-v] [command-specific arguments]
DESCRIPTION
The vmadm tool allows you to interact with virtual machines on a Smar‐
tOS system. All 3 of: OS Virtual Machines (SmartOS zones), LX Virtual
Machines and KVM Virtual Machines can be managed. vmadm allows you to
create, inspect, modify and delete virtual machines on the local sys‐
tem.
IMPORTANT: Support for LX VMs is currently limited and experimental.
This means it is very likely to change in major ways without notice.
Also: not all the LX functionality that is implemented is documented
yet. The documentation will be updated as things stablize.
The primary reference for a VM is its UUID. Most commands operate on
VMs by UUID. In SmartOS, there are included bash tab-completion rules
so that you can tab-complete UUIDs rather than having to type them out
for every command.
COMMANDS
The following commands and options are supported:
create [-f <filename>]
Create a new VM on the system. Any images/datasets referenced must
already exist on the target zpool. Input must be JSON You can either
pass in a file with the -f parameter or redirect stdin from something
with JSON. Create will refuse to create a VM if no file is specified
and stdin is a tty.
See the ´PROPERTIES´ or ´EXAMPLES´ sections below for details on what
to put in the JSON payload.
create-snapshot <uuid> <snapname>
Support for snapshots is currently experimental. It only works for OS
VMS which also have no additional datasets.
The <snapname> parameter specifies the name of the snapshot to take
of the specified VM. The snapname must be 64 characters or less and
must only contain alphanumeric characters and characters in the set
[-_.:%] to comply with ZFS restrictions.
You can use delete-snapshot or rollback-snapshot in the future on a
snapshot you´ve created with create-snapshot, so long as that snapshot
still exists.
See the ´SNAPSHOTS´ section below for some more details on how to use
these snapshots, and their restrictions.
console <uuid>
Connect to the text console for a running VM. For OS VMs, this will be
the zone console. For KVM VMs, this will be the serial console and your
VM will need to be setup with getty or similar running on the first
serial device. Not yet supported on LX VMs.
To end the serial console session hit CTRL-]. For OS VMs, you´ll need
to do this at the start of a line, so generally this means pressing:
ENTER then CTRL-] then a dot character. For KVM VMs you should just
need to press CTRL-] by itself.
delete <uuid>
Delete the VM with the specified UUID. The VM and any associated
storage including zvols and the zone filesystem will be removed.
If you have set the indestructible_zoneroot or indestructible_delegated
flags on a VM it *cannot* be deleted until you have unset these flags
with something like:
vmadm update <uuid> indestructible_zoneroot=false
vmadm update <uuid> indestructible_delegated=false
to remove the snapshot and holds.
Note: ´vmadm delete´ command is not interactive, take care to delete the
right VM.
delete-snapshot <uuid> <snapname>
Support for snapshots is currently experimental. It only works for OS
VMS which also have no additional datasets.
This command deletes the ZFS snapshot that exists with the name
<snapname> from the VM with the specified uuid. You cannot undo this
operation and it will no longer be possible to rollback to the specified
snapshot.
See the ´SNAPSHOTS´ section below for some more details on how to use
these snapshots, and their restrictions.
get <uuid>
Output the JSON object describing a VM. The JSON object will be dumped
to stdout. The output object can then be further handled by the json(1)
command if desired.
info <uuid> [type,...]
The info command operates on running KVM VMs only. It talks to the
vmadmd(1m) daemon and requests some information about the running VM.
The information is output to stdout as a JSON object with member
objects for each type specified. If no types are specified, all info
is included. The type values can be separated either by commas or
spaces.
The info types available are:
all:
Explicitly include all of the other types.
block:
Information about the block devices attached to this VM.
blockstats:
Counters for blocks read/written, number of operations and highest
write offset for each block device.
chardev:
Information about the special character devices attached to this
VM.
cpus:
Information about the virtual CPUs attached to this VM.
kvm:
Information about the availability of the KVM driver in this VM.
pci:
Information about each device on the virtual PCI bus attached to
this VM.
spice:
The IP, port and VNC display number for the TCP socket we´re
listening on for this VM. If spice is enabled.
version:
Qemu version information.
vnc:
The IP, port and VNC display number for the TCP socket we´re
listening on for this VM. If VNC is enabled.
list [-p] [-H] [-o field,...] [-s field,...] [field=value ...]
The list command can list the VMs on a system in a variety of ways. The
filters, order and sort options are all based on the properties of VMs.
See the PROPERTIES section below for the list of keys allowed. All
those listed there as ´listable´ can be used as keys for filtering,
sorting or ordering.
The list command always operates on a set of VMs which is limited by a
filter. By default the filter is empty so all VMs are listed. You add
filters by specifying key=value pairs on the cmdline. You can also
match filters by regular expression by using key=~value and making
value be a regular expression. You can add as many filters as you want
and only VMs that match all the filter parameters will be shown.
The fields output are controlled with the -o option which specifies the
order. The default order is ´uuid,type,ram,state,alias´. If you
specify your own order with the -o option, this order is replaced so
any fields from the default you want to keep in your output you´ll have
to add them to your list of fields.
The order of the rows in the output is controlled through the -s option
which determines the sort order. The default sort order is ´ram,uuid´
which means VMs will be first sorted by RAM and then VMs which have
the same RAM value will be sorted by uuid. You can also choose to have
a field sorted in descending order by prefixing that field name with a
´-´ character. Thus an order like ´-ram,uuid´ would do the same as the
default except be sorted with the highest RAM value first.
The two other options which you can specify for the list command are
´-p´ which chooses parsable output. With this flag set, output is
separated by ´:´ characters instead of being lined up in columns. This
option also disables printing of the header.
If you would like to disable the printing of the header in the normal
output for some reason, you can do so with the ´-H´ option.
You can see several examples using order, sort and selection in the
EXAMPLES section below.
lookup [-j|-1] [-o field,field,..] [field=value ...]
The lookup command is designed to help you find VMs. It takes a set of
filter options in the same format as the list command. This means you
specify them with key=value pairs on the command line and can use the
key=~value format to specify a regular expression value. The VMs which
match all of your filter parameters will be output.
The default output is a single column list of UUIDs for VMs that match
the filter. This allows you to do things like:
for vm in $(vmadm lookup type=KVM state=running); do
echo -n "${vm} "
vmadm info ${vm} vnc | json vnc.display
done
based on the output. If you want to use the output as JSON, you can add
the -j parameter. With that flag set, the output will be a JSON array
of VM objects containing the same JSON data as the ´get´ command for
each VM matched.
When the -j flag is passed, you can also limit the fields in the objects
of the output array. To do so, use the -o option. For example if you
use:
vmadm lookup -j -o uuid,brand,quota
the objects in the output array will only have the uuid, brand and quota
members. Where possible vmadm optimizes the lookups such that not
including fields in the output means it won´t have to do the potentially
expensive operations to look them up. By default (without -o) all fields
are included in the objects.
If you pass the -1 parameter, lookup should only return 1 result. If
multiple results are matched or 0 results are matched, an error will
be returned and the exit status will be non-zero.
See the PROPERTIES section below for the list of keys allowed. All
those listed there as ´listable´ can be used as keys for filtering.
reboot <uuid> [-F]
Reboot a VM. The default reboot will attempt a graceful stop of the VM
and when the VM has stopped, it will be booted again. This ensures that
processes within the VM are given an opportunity to shut down correctly
in attempt to minimize data loss.
For OS VMs, the shutdown command will be run within the zone with the
cmdline ´/usr/sbin/shutdown -y -g 0 -i 6´ which will cause the VM to
reboot after shutting down.
For KVM VMs, vmadmd will act as a helper here for the reboot in the
same manner as described below for the ´stop´ command.
If for some reason you are unable or do not want to do a graceful
reboot you can add the ´-F´ parameter to do a forced reboot. This
reboot will be much faster but will not necessarily give the VM any
time to shut down its processes.
rollback-snapshot <uuid> <snapname>
Support for snapshots is currently experimental. It only works for OS
VMS which also have no additional datasets.
This command rolls the dataset backing the the VM with the specified
uuid back to its state at the point when the snapshot with snapname was
taken. You cannot undo this except by rolling back to an even older
snapshot if one exists.
IMPORTANT: when you rollback to a snapshot, all other snapshots newer
than the one you´re rolling back to will be deleted. It will no longer
be possible to rollback to a snapshot newer than <snapname> for this VM.
Also note: your VM will be stopped if it is running when you start a
rollback-snapshot and will be booted after the snapshot has been
restored.
See the ´SNAPSHOTS´ section below for some more details on how to use
these snapshots, and their restrictions.
start <uuid> [option=value ...]
Start a VM which is in the ´off´ state. For OS VMs, this doesn´t take
any arguments. For KVM VMs, it is possible to specify some additional
boot parameters for the VM with this tool. These can be:
order=cdn[,once=d]
This option allows you to change the boot order for the VM for the
current boot. The order options are ´c´ for the hard disk, ´d´
for the first CD-ROM drive and ´n´ for network boot. So the order
´cdn´ means boot the hard disk and if that fails try cdrom and if
that fails try network boot.
You can also add a ´,once=X´ option where ´X´ is one of the same
order options. This will set the boot order once and if the VM is
rebooted (even from inside) the order will go back to the default.
This is especially useful for installation media, since you can add
,once=d to boot off an ISO image once and then after the install
is complete you will boot on the hard drive.
The order= option can only be specified once per boot.
cdrom=/path/to/image.iso,[ide|scsi|virtio]
This option lets you add a virtual CD-ROM disk to a VM for this
boot only. The path specified is evaluated within the zoneroot of
the VM so /image.iso will actually be something like the path
/zones/<uuid>/root/image.iso from the global zone.
The second part of this parameter (after the comma) indicates which
model the CD-ROM drive should be. You should choose ide in most
cases.
You can specify multiple cdrom options when booting a VM. They will
be attached in the order they appear on the cmdline.
disk=/path/to/disk,[ide|scsi|virtio]
This option lets you add an additional disk to a VM for this boot
only. The path specified is evaluated within the zoneroot of the
VM so /raw.img will actually be something like the path
/zones/<uuid>/root/raw.img from the global zone.
The second part of this parameter (after the comma) indicates which
model the virtual drive should be. You should choose virtio when
you know that the VM supports it, and ide or scsi otherwise
depending on the drivers supported in the guest.
You can specify multiple disk options when booting a VM. They will
be attached in the order they appear on the cmdline.
stop <uuid> [-F]
Stop a VM. The default stop will attempt to be graceful. This ensures
that processes within the VM are given an opportunity to shut down
correctly in attempt to minimize data loss.
For OS VMs, the shutdown command will be run within the zone with the
cmdline ´/usr/sbin/shutdown -y -g 0 -i 5´ which will cause the VM to
go to the ´off´ state after shutting down all processes.
For KVM VMs, vmadmd will act as a helper here. We send a powerdown
message via vmadmd to the running qemu process. Qemu then sends the
ACPI signal to the guest kernel telling it to shut down. In case the
guest kernel ignores this or for some reason does not receive this
request we mark the VM with a transition property indicating that we
tried to shut it down. This transition marker also includes an expiry.
If vmadmd sees a VM that has a transition but reaches the expiry before
actually turning off, it re-sends the stop command with the -F option.
If for some reason you are unable or do not want to do a graceful stop
you can also add the ´-F´ parameter via to do a forced stop. This stop
will be much faster (especially for KVM) but will not necessarily give
the VM any time to shut down its processes.
sysrq <uuid> <nmi|screenshot>
This command is only available for KVM VMs. For those it exposes the
ability to send the guest OS Kernel an non maskable interrupt (NMI) or
take a screenshot of the virtual console.
To send an NMI, you can run: vmadm sysrq <uuid> nmi
To take a screenshot: vmadm sysrq <uuid> screenshot
Screenshots will end up under the directory zonepath for the VM, at:
<zonepath>/root/tmp/vm.ppm from the global zone.
update <uuid> [-f <filename>]
update <uuid> property=value [property=value ...]
This command allows you to update properties of an existing VM. The
properties which can be updated are listed below in the PROPERTIES
section with the ´updatable: yes´ property.
To update properties, you can either pass a file containing a JSON
object as the argument to the -f option on the cmdline, send a JSON
object on stdin (though it will refuse work if stdin is a tty), or
pass property=value arguments on the cmdline.
If you pass in a JSON object, that object should be formatted in the
same manner as a create payload. The only exception is with fields
that are themselves objects: VM NICs, KVM VM disks, customer_metadata,
internal_metadata, tags and routes. In the the case of the "simple"
properties ´tags´, ´customer_metadata´, ´internal_metadata´ and
´routes´ which are key-value pairs, there are 2 special payload members:
set_tags || set_customer_metadata
|| set_internal_metadata || set_routes
remove_tags || remove_customer_metadata ||
remove_internal_metadata || remove_routes
which can add/update or remove entries from key/value sets. To add an
entry, include it in the set_X object with a simple string value. To
remove an object from these dictionaries, include its name in a list
as the value to remove_X. For example, to add a tag ´hello´ with value
´world´, your JSON would look like this:
{"set_tags": {"hello": "world"}}
then to change the value for this key you´d do:
{"set_tags": {"hello": "universe"}}
and finally to remove this key you´d do:
{"remove_tags": ["hello"]}
The same pattern is used for customer_metadata, internal_metadata and
routes.
In the case of nics and disks, there are 3 special objects:
add_disks || add_nics
remove_disks || remove_nics
update_disks || update_nics
For NICs for example, you can include an array of NIC objects with the
parameter add_nics in your input. Those NICs would get added to the VM.
For update you also pass in a new NIC object but only need to specify
the "mac" parameter (to identify which NIC to update) and the
properties that you want to change. If you need to change the MAC
address itself, you´ll need to add a new NIC with the same properties
and a different MAC, and remove the existing one. To remove a NIC, the
remove_nics property should be an array of MAC addresses only (not NIC
objects).
For updating disks, you use the same format as described above for NICs
except that the options are add_disks, remove_disks and update_disks
and instead of "mac" these will be keyed on "path".
Those fields marked in the PROPERTIES section below as updatable and
modified with ´(live update)´ mean that when you update the property
the change takes effect immediately for the VM without the VM being
restarted. Other properties will require a reboot in order to take
effect.
validate create [-f <filename>]
validate update <brand> [-f <filename>]
This command allows you to validate your JSON payloads before calling
create or update. You must specify the action for which your payload is
intended (create or update) as the validation rules are different. In
addition, when validating an update payload, you must pass the brand
parameter as validation rules vary based on brand.
If no -f <filename> is specified the payload is expected to be passed
on stdin. If -f <filename> is specfied, the payload to validate will
be read from the file with that name. Output from this command in the
case the payload is valid will be something like:
"VALID create payload for joyent brand VMs."
and the exit code will be 0. When the payload is not valid the exit code
will be 1 and you will get back a json object which will have at least
one of the following members:
´bad_brand´
The brand argument you passed to validate is invalid.
´bad_properties´
This is an array of payload properties which are not valid for the
specified action.
´bad_values´
This is an array of payload properties which had unacceptable values.
´missing_properties´
This is an array of the payload properties which are required for the
given action but are missing from the specified payload.
consult the PROPERTIES section below for help correcting errors in your
payload.
SNAPSHOTS
Snapshots are currently only implemented for OS VMs, and only for those
that do not utilize delegated datasets or any other datasets other than
the zoneroot dataset.
When you create a snapshot with create-snapshot, it will create a ZFS
snapshot of that dataset with the name dataset@vmsnap-<snapname> and the
.snapshots member of VM objects returned by things like vmadm get will
only include those snapshots that have been created using this pattern.
That allows vmadm to distinguish between snapshots it has taken and
snapshots that could have been taken using other tools.
To delete a snapshot you can use the delete-snapshot command. That will
destroy the snapshot in ZFS and it will automatically be removed from the
machine´s snapshot list. It will no longer be possible to rollback to it.
To rollback a VM to its state at the time of a previous snapshot, you can
use the rollback-snapshot command. This will stop the VM rollback the
zoneroot dataset to the specified snapshot and start the VM again.
IMPORTANT: rollback-snapshot will automatically delete all snapshots newer
than the one you´re rolling back to. This cannot be undone.
PROPERTIES
Every VM has a number of properties. The properties for a VM can be listed
with the ´vmadm get <uuid>´ command. Some of these properties can be
included in a create payload, some can be included in the output or be used
to sort output for the ´vmadm list´ command. Not all fields will be
included for all VMs. Below the fields are marked as:
type -- type of the properties value.
vmtype -- types of VM (KVM, LX, OS) for which this property applies.
listable -- if they can be included in the -o or -s lists for the
´vmadm list´ command.
create -- if the field can be included in a create payload.
update -- if the field can be updated using the ´vmadm update´ command.
Some fields are also marked (live update) in which case,
updates affect the behaviour of the running machine. Other
updatable fields will either not affect VM operation or
require a reboot of the VM to do so.
default -- if the field has a default value, this will explain what
that value is.
alias:
An alias for a VM which is for display/lookup purposes only. Not
required to be unique.
type: string
vmtype: OS,KVM
listable: yes
create: yes
update: yes
archive_on_delete:
When archive_on_delete is set to ´true´ and the VM is deleted and the
zones/archive dataset exists and is mounted on /zones/archive, we will
extract debug information from the zone before destroying it.
Information saved includes cores, the JSON as output by ´vmadm get´,
the zone´s XML file from /etc/zones, SMF logs, qemu logs (for KVM),
the startvm script (for KVM), the properties from all the zone´s
datasets, metadata, tags and /var/adm/messages. In the future the list
may change. The files specified will be written to the directory
/zones/archives/<uuid>.
type: boolean
vmtype: OS,KVM
listable: no
create: yes
update: yes
default: false
autoboot:
Controls whether or not a VM is booted when the system is rebooted.
This property can be set with the initial create but any time the VM is
started this will also get set true and when the VM is stopped it will
get set false. This is to ensure that the compute node will always
reboot into the intended state.
type: boolean
vmtype: OS,KVM
listable: yes
create: yes
update: yes
billing_id:
An identifier intended to help identify which billing category this VM
should fall into.
type: string (UUID)
vmtype: OS,KVM
listable: yes
create: yes
update: yes
default: 00000000-0000-0000-0000-000000000000
boot:
This option allows you to set the boot order for KVM VMs. The format is
the same as described above for the order parameter to the ´start´
command.
type: string
vmtype: KVM
listable: no
create: yes
update: yes
default: ´order=cd´
brand:
This will be one of ´joyent´, ´joyent-minimal´ or ´sngl´ for OS
virtualization and ´kvm´ for full hardware virtualization. This is a
required value for VM creation.
type: string (joyent|joyent-minimal|kvm|sngl)
vmtype: OS,KVM
listable: yes
create: yes
update: no
cpu_cap:
Sets a limit on the amount of CPU time that can be used by a VM. The
unit used is the percentage of a single CPU that can be used by the VM.
Eg. a value of 300 means up to 3 full CPUs.
type: integer (percentage of single CPUs)
vmtype: OS,KVM
listable: yes
create: yes
update: yes (live update)
cpu_shares:
Sets a limit on the number of fair share scheduler (FSS) CPU shares for
a VM. This value is relative to all other VMs on the system, so a value
only has meaning in relation to other VMs. If you have one VM with a
a value 10 and another with a value of 50, the VM with 50 will get 5x
as much time from the scheduler as the one with 10 when there is
contention.
type: integer (number of shares)
vmtype: OS,KVM
listable: yes
create: yes
update: yes (live update)
default: 100
cpu_type:
For KVM VMs, this controls the type of the virtual CPU exposed to the
guest. If the value is ´host´ the guest will see the same CPU type and
flags as are seen on the host.
type: string (qemu64|host)
listable: yes
vmtype: KVM
create: yes
update: yes
default: qemu64
create_timestamp:
The time at which the VM was created in ISO 8601 format.
type: string (format: ´2011-12-31T06:38:42.457Z´)
vmtype: OS,KVM
listable: yes
create: no (automatically added)
update: no
default: always set to current time at VM.create().
server_uuid:
This is the UUID of the compute node on which the VM currently exists.
It is most useful when pulled from sources external to the GZ (whether
in the VM, or from another node).
type: string (compute node´s UUID)
vmtype: OS,KVM
listable: no
create: no
update: no
default: this is always pulled when the object is loaded.
customer_metadata:
This field allows metadata to be set and associated with this VM. The
value should be an object with only top-level key=value pairs.
NOTE: for historical reasons, do not put keys in here that match the
pattern *_pw. Those keys should go in internal_metadata instead.
type: JSON Object (key: value)
vmtype: OS,KVM
listable: no
create: yes
update: yes (but see special notes on update command)
default: {}
image_uuid:
This should be a UUID identifying the image for the VM if a VM was
created from an image.
NOTE: when this is passed for KVM VMs, it specifies the *zone root*
dataset which is not visible from within the VM. The user-visible
dataset will be the one specified through the disks.*.image_uuid.
Normally you do *not* want to set this for KVM.
type: string (UUID)
vmtype: OS,KVM
listable: yes
create: yes
update: no
datasets:
If a VM has extra datasets available to it (eg. if you specified the
delegate_dataset option when creating) the list and get output will
include the information about that dataset under this key.
type: string (dataset name)
vmtype: OS
listable: no
create: no (use delegate_dataset to include one)
update: no
delegate_dataset:
This property indicates whether we should delegate a ZFS dataset to an
OS VM. If true, the VM will get a dataset <zoneroot dataset>/data (by
default: zones/<uuid>/data) added to it. This dataset will be also be
mounted on /<zoneroot dataset>/data inside the zone (again by default:
/zones/<uuid>/data) but you can change this by setting the mountpoint
option on the dataset from within the zone with zfs(1M). When using
this option, sub-datasets can be created, snapshots can be taken and
many other options can be performed on this dataset from within the
VM.
type: boolean
vmtype: OS
listable: no
create: yes
update: no
default: false
disks:
When creating a KVM VM or getting a KVM VM´s JSON, you will use this
property. This is an array of ´disk´ objects. The properties available
are listed below under the disks.*.<property> options. If you want to
update disks, see the special notes in the section above about the
´upgrade´ command.
When adding or removing disks, the disks will be available to the VM in
the order that the disks are included in the disks or add_disks array.
To use these properties in a list output or lookup, use the format:
disks.*.size # for lookup matching any disk
disks.0.size # for list output or lookup of a specific disk
disks.*.block_size:
Specifies the block size for the disk. This property can only be set at
disk creation time and cannot be changed without destroying the disk
and creating a new one.
Important: this property cannot be set on disks that have an image_uuid
parameter as the image being cloned will already have the ZFS
volblocksize property set.
type: integer (block size in bytes, 512 to 131072, must be power of 2)
vmtype: KVM
listable: no
create: yes
update: no (except when adding new disks)
default: 8192
disks.*.boot:
Specifies whether this disk should be bootable (only one disk should).
type: boolean
vmtype: KVM
listable: yes (see above)
create: yes
update: yes (special, see description in ´update´ section above)
default: no
disks.*.compression:
Specifies a compression algorithm used for this disk. This has the same
details, warnings and caveats as the global zfs_root_compression option
below but only affects a single disk on the VM.
See zfs_root_compression section below for more details.
type: string one of: "on,off,gzip,gzip-N,lz4,lzjb,zle"
vmtype: KVM
listable: no
create: yes
update: yes (see caveat in zfs_root_compression section below)
default: off
disks.*.nocreate:
This parameter indicates whether or not the disk should be created. It
only makes sense for disks with media type ´disk´. For media type
´cdrom´ the device is not created. It also can only be set when
creating a disk.
type: boolean
vmtype: KVM
listable: no
create: yes
update: no (except when adding new disks)
default: false (new zvol is created when media type is ´disk´)
disks.*.image_name:
Name of dataset from which to clone this VM´s disk. You should specify
either this and ´image_size´ and ´image_uuid´, or ´size´ for a disk.
type: string
vmtype: KVM
listable: yes (see above)
create: yes
update: yes (special, see description in ´update´ section above)
default: no
disks.*.image_size:
The size of the image from which we will create this disk. When neither
size nor image_size is passed for a disk but an image_uuid is, and that
image is available through imgadm, the image_size value from the
manifest will be set as image_size.
Important: image_size is required (unless you rely on imgadm) when you
include image_uuid for a disk and not allowed when you don´t.
type: integer (size in MiB)
vmtype: KVM
listable: yes (see above)
create: yes
update: yes (special, see description in ´update´ section above)
default: no (loaded from imgadm if possible)
disks.*.image_uuid:
UUID of dataset from which to clone this VM´s disk. Note: this image´s
UUID must show up in the ´imgadm list´ output in order to be valid.
type: string (UUID)
vmtype: KVM
listable: yes (see above)
create: yes
update: yes (special, see description in ´update´ section above)
default: no

fs_allowed:
This option allows you to specify filesystem types this zone is allowed
to mount. For example on a zone for building SmartOS you probably want
to set this to: "ufs,pcfs,tmpfs". To unset this property, set the
value to the empty string.
type: string (comma separated list of filesystem types)
vmtype: OS
listable: no
create: yes
update: yes (requires zone reboot to take effect)
hostname:

type: string (hostname)
vmtype: OS,KVM
listable: yes
create: yes
update: yes (but does nothing for OS VMs)
default: the value of zonename
internal_metadata:
This field allows metadata to be set and associated with this VM. The
value should be an object with only top-level key=value pairs. The
intention is that customer_metadata contain customer modifiable keys
whereas internal_metadata is for operator generated keys.
NOTE: for historical reasons, when a user in a zone does:
mdata-get name_pw
where the key ends with ´_pw´, the key is looked up in internal_metadata
instead of customer_metadata.
type: JSON Object (key: value)
vmtype: OS,KVM
listable: no
create: yes
update: yes (but see special notes on update command)
default: {}
indestructible_delegated:
When set this property adds an @indestructible snapshot to the delegated
(<zfs_filesystem>/data) dataset and sets a zfs hold on that snapshot.
This hold must be removed before the VM can be deleted enabling a
two-step deletion. Eg. to delete a VM where this has been set, you would
need to:
vmadm update <uuid> indestructible_delegated=false
vmadm delete <uuid>
instead of being able to do the delete on its own. The property will
only show up in VM objects when set true.
NOTE: if the hold on the @indestructible dataset is removed manually
from the GZ or from within the zone, this would also remove this flag
and allow the VM to be deleted.
type: boolean
vmtype: KVM,LX,OS
listable: yes
create: yes
update: yes
default: false
indestructible_zoneroot:
When set this property adds an @indestructible snapshot to the zoneroot
(zfs_filesystem) dataset and sets a zfs hold on that snapshot. This hold
must be removed before the VM can be deleted *or reprovisioned*. Eg. to
delete a VM where this has been set, you would need to:
vmadm update <uuid> indestructible_zoneroot=false
vmadm delete <uuid>
instead of being able to do the delete on its own. The property will
only show up in VM objects when set true.
NOTE: if the hold on the @indestructible dataset is removed manually
from the GZ, this would also remove this flag and allow the VM to be
deleted.

with DHCP responses.
type: array
vmtype: OS,KVM
listable: no
create: yes
update: yes
routes:
This is a key-value object that maps destinations to gateways. These
will be set as static routes in the VM. The destinations can be either
IPs or subnets in CIDR form. The gateways can either be IP addresses, or
can be of the form "nics[0]", which specifies a link-local route on the
numbered nic in that VM´s nics array (the first nic is 0). As an

vmtype: KVM
listable: no
create: yes
update: yes
default: 0
zfs_data_compression:
Specifies a compression algorithm used for this VM´s data dataset. This
option affects only the delegated dataset and therefore only makes
sense when the VM has been created with the delegate_dataset option.
The caveats and warnings in the zfs_root_compression section below also
apply to this option.
type: string one of: "on,off,gzip,gzip-N,lz4,lzjb,zle"

dataset as added by the delegate_dataset option.
The warnings and caveats for zfs_root_recsize also apply to this
option. You should read and understand those before using this.
type: integer (record size in bytes, 512 to 131072, must be power of 2)
vmtype: OS (and only with a delegated dataset)
listable: no
create: yes
update: yes (see caveat below under zfs_root_recsize)
default: 131072 (128k)
zfs_io_priority:
This sets an IO throttle priority value relative to other VMs. If one
VM has a value X and another VM has a value 2X, the machine with the
X value will have some of its IO throttled when both try to use all
available IO.
type: integer (relative value)
vmtype: OS,KVM
listable: yes
create: yes
update: yes (live update)
default: 100
zfs_root_compression:
Specifies a compression algorithm used for this VM´s root dataset. This
option affects only the zoneroot dataset. Setting to ´on´ is equivalent
to setting to ´lzjb´. If you want more information about the specific
compression types, see the man page for zfs(1m).
WARNING: If you change this value for an existing VM, only *new* data
will be compressed. It will not rewrite existing data compress.
NOTE: to change this property for KVM, see disks.*.zfs_compression
above.
type: string one of: "on,off,gzip,gzip-N,lz4,lzjb,zle"
vmtype: OS
listable: no
create: yes
update: yes (see warning above)
default: off
zfs_root_recsize:
Specifies a suggested block size for files in the root file system.
This property is designed solely for use with database workloads that
access files in fixed-size records. ZFS automatically tunes block sizes
according to internal algorithms optimized for typical access patterns.
If you have a delegated dataset (with the delegate_dataset option) you
should consider leaving this unset and setting zfs_data_recsize
instead.
WARNING: Use this property only if you know exactly what you´re doing
as it is very possible to have an adverse effect performance when
setting this incorrectly. Also, when doing an update, keep in mind that
changing the file system´s recordsize affects only files created
after the setting is changed; existing files are unaffected.
NOTE: to change this property for KVM, see disks.*.zfs_recsize above.
type: integer (record size in bytes, 512 to 131072, must be power of 2)
vmtype: OS
listable: no
create: yes
update: yes (see caveat above)
default: 131072 (128k)
zone_state:
This property will show up when fetching a VMs JSON. this shows the
state of the zone in which this VM is contained. eg. ´running´. It
can be different from the ´state´ value in several cases.
type: string
vmtype: KVM
listable: yes
create: no
update: no
zonepath:
This property will show up in JSON representing a VM. It describes the
path in the filesystem where you will find the VMs zone dataset. For OS
VMs all VM data will be under this path, for KVM VMs this is where
you´ll find things such as the logs and sockets for a VM.
type: string (path)
vmtype: OS,KVM
listable: no
create: no (automatic)
update: no
zonename:
This property indicates the zonename of a VM. The zonename is a private
property and not intended to be used directly. For OS VMs you can set
this property with the create payload, but such use is discouraged.
type: string
vmtype: OS,KVM
listable: yes
create: yes (OS VMs only)
update: no
default: value of uuid
zoneid:
This property will show up in a JSON payload and can be included in
list output. It is however a value that is used internally to the
system and primarily exists to aid debugging. This value will change
whenever the VM is stopped or started. Do not rely on this value.
type: integer
vmtype: OS,KVM
listable: yes
create: no
update: no
zpool:
This defines which ZFS pool the VM´s zone dataset will be created in
For OS VMs, this dataset is where all the data in the zone will live.
For KVM VMs, this is only used by the zone shell that the VM runs in.
type: string (zpool name)
vmtype: OS,KVM
listable: yes
create: yes
update: no
default: zones
