salt.modules.virt¶

Work with virtual machines managed by libvirt

depends: libvirt Python module

Connection¶

The connection to the virtualization host can be either setup in the minion configuration, pillar data or overridden for each individual call.

By default, the libvirt connection URL will be guessed: the first available libvirt hypervisor driver will be used. This can be overridden like this:

virt:
  connection:
    uri: lxc:///

If the connection requires an authentication like for ESXi, this can be defined in the minion pillar data like this:

virt:
  connection:
    uri: esx://10.1.1.101/?no_verify=1&auto_answer=1
    auth:
      username: user
      password: secret

Connecting with SSH protocol¶

Libvirt can connect to remote hosts using SSH using one of the ssh, libssh and libssh2 transports. Note that libssh2 is likely to fail as it doesn't read the known_hosts file. Libvirt may also have been built without libssh or libssh2 support.

To use the SSH transport, on the minion setup an SSH agent with a key authorized on the remote libvirt machine.

Per call connection setup¶

New in version 2019.2.0.

All the calls requiring the libvirt connection configuration as mentioned above can override this configuration using connection, username and password parameters.

This means that the following will list the domains on the local LXC libvirt driver, whatever the virt:connection is.

salt 'hypervisor' virt.list_domains connection=lxc:///

The calls not using the libvirt connection setup are:

seed_non_shared_migrate
virt_type
is_*hyper
all migration functions
libvirt ESX URI format
libvirt URI format
libvirt authentication configuration

New in version 3001.
efi: A boolean value.

New in version sodium.

Network Interfaces Definitions

Network interfaces dictionaries can contain the following properties:

name: Name of the network interface. This is only used as a key to merge with the profile data
type: Network type. One of 'bridge', 'network'
source: The network source, typically the bridge or network name
mac: The desired mac address, computed if None (Default: None).
model: The network card model (Default: depends on the hypervisor)

Disks Definitions

Disk dictionaries can contain the following properties:

name

Name of the disk. This is mostly used in the name of the disk image and as a key to merge with the profile data.

format

Format of the disk image, like 'qcow2', 'raw', 'vmdk'. (Default: depends on the hypervisor)

size

Disk size in MiB

pool

Path to the folder or name of the pool where disks should be created. (Default: depends on hypervisor and the virt:storagepool configuration)

Changed in version 3001.

If the value contains no '/', it is considered a pool name where to create a volume. Using volumes will be mandatory for some pools types like rdb, iscsi, etc.

model

One of the disk busses allowed by libvirt (Default: depends on hypervisor)

See the libvirt disk element documentation for the allowed bus types.

image

Path to the image to use for the disk. If no image is provided, an empty disk will be created (Default: None)

Note that some pool types do not support uploading an image. This list can evolve with libvirt versions.

overlay_image

True to create a QCOW2 disk image with image as backing file. If False the file pointed to by the image property will simply be copied. (Default: False)

Changed in version 3001.

This property is only valid on path-based disks, not on volumes. To create a volume with a backing store, set the backing_store_path and backing_store_format properties.

backing_store_path

Path to the backing store image to use. This can also be the name of a volume to use as backing store within the same pool.

New in version 3001.

backing_store_format

Image format of the disk or volume to use as backing store. This property is mandatory when using backing_store_path to avoid problems

New in version 3001.

source_file

Absolute path to the disk image to use. Not to be confused with image parameter. This parameter is useful to use disk images that are created outside of this module. Can also be None for devices that have no associated image like cdroms.

Changed in version 3001.

For volume disks, this can be the name of a volume already existing in the storage pool.

device

Type of device of the disk. Can be one of 'disk', 'cdrom', 'floppy' or 'lun'. (Default: 'disk')

hostname_property

When using ZFS volumes, setting this value to a ZFS property ID will make Salt store the name of the virtual machine inside this property. (Default: None)

sparse_volume

Boolean to specify whether to use a thin provisioned ZFS volume.

Example profile for a bhyve VM with two ZFS disks. The first is cloned from the specified image. The second disk is a thin provisioned volume.

virt:
  disk:
    two_zvols:
      - system:
          image: zroot/bhyve/CentOS-7-x86_64-v1@v1.0.5

          hostname_property: virt:hostname
          sparse_volume: True

Graphics Definition

The graphics dictionary can have the following properties:

type

Graphics type. The possible values are none, 'spice', 'vnc' and other values allowed as a libvirt graphics type (Default: None)

See the libvirt graphics element documentation for more details on the possible types.

port

Port to export the graphics on for vnc, spice and rdp types.

tls_port

Port to export the graphics over a secured connection for spice type.

listen

Dictionary defining on what address to listen on for vnc, spice and rdp. It has a type property with address and None as possible values, and an address property holding the IP or hostname to listen on.

By default, not setting the listen part of the dictionary will default to listen on all addresses.

CLI Example

salt 'hypervisor' virt.init vm_name 4 512 salt://path/to/image.raw
salt 'hypervisor' virt.init vm_name 4 512 /var/lib/libvirt/images/img.raw
salt 'hypervisor' virt.init vm_name 4 512 nic=profile disk=profile

Create libvirt pool.

Parameters

name -- Pool name
ptype -- Pool type. See libvirt documentation for the possible values.
target -- Pool full path target
permissions -- Permissions to set on the target folder. This is mostly used for filesystem-based pool types. See Permissions definition for more details on this structure.
source_devices --
List of source devices for pools backed by physical devices. (Default: None)

Each item in the list is a dictionary with path and optionally part_separator keys. The path is the qualified name for iSCSI devices.

Report to this libvirt page for more information on the use of part_separator
source_dir -- Path to the source directory for pools of type dir, netfs or gluster. (Default: None)
source_initiator --
Initiator IQN for libiscsi-direct pool types. (Default: None)

New in version 3000.
source_adapter --
SCSI source definition. The value is a dictionary with type, name, parent, managed, parent_wwnn, parent_wwpn, parent_fabric_wwn, wwnn, wwpn and parent_address keys.

The parent_address value is a dictionary with unique_id and address keys. The address represents a PCI address and is itself a dictionary with domain, bus, slot and function properties. Report to this libvirt page for the meaning and possible values of these properties.
source_hosts -- List of source for pools backed by storage from remote servers. Each item is the hostname optionally followed by the port separated by a colon. (Default: None)
source_auth --
Source authentication details. (Default: None)

The value is a dictionary with type, username and secret keys. The type can be one of ceph for Ceph RBD or chap for iSCSI sources.

The secret value links to a libvirt secret object. It is a dictionary with type and value keys. The type value can be either uuid or usage.

Examples:
```
source_auth={
    'type': 'ceph',
    'username': 'admin',
    'secret': {
        'type': 'uuid',
        'value': '2ec115d7-3a88-3ceb-bc12-0ac909a6fd87'

    'username': 'myname',
    'secret': {
        'type': 'usage',
        'value': 'mycluster_myname'
    }
}
```
Since 3000, instead the source authentication can only contain username and password properties. In this case the libvirt secret will be defined and used. For Ceph authentications a base64 encoded key is expected.
source_name -- Identifier of name-based sources.
source_format --
String representing the source format. The possible values are depending on the source type. See libvirt documentation for the possible values.
start -- Pool start (default True)
transient -- When True, the pool will be automatically undefined after being stopped. Note that a transient pool will force start to True. (Default: False)
connection -- libvirt connection URI, overriding defaults
username -- username to connect with, overriding defaults
password -- password to connect with, overriding defaults

salt.modules.virt.vm_state(vm_=None, **kwargs)¶

Return list of all the vms and their state.

If you pass a VM name in as an argument then it will return info for just the named VM, otherwise it will return all VMs.

Parameters

vm -- name of the domain
connection --
libvirt connection URI, overriding defaults

New in version 2019.2.0.
username --
username to connect with, overriding defaults

New in version 2019.2.0.
password --
password to connect with, overriding defaults

New in version 2019.2.0.

CLI Example:

salt '*' virt.vm_state <domain>

salt.modules.virt.volume_define(pool, name, size, allocation=0, format=None, type=None, permissions=None, backing_store=None, nocow=False, **kwargs)¶

Create libvirt volume.

Parameters

pool -- name of the pool to create the volume in
name -- name of the volume to define
size -- capacity of the volume to define in MiB
allocation -- allocated size of the volume in MiB. Defaults to 0.
format -- volume format. The allowed values are depending on the pool type. Check the virt.pool_capabilities output for the possible values and the default.
type -- type of the volume. One of file, block, dir, network, netdiri, ploop or None. By default, the type is guessed by libvirt from the pool type.
permissions -- Permissions to set on the target folder. This is mostly used for filesystem-based pool types. See Permissions definition for more details on this structure.
backing_store --
dictionary describing a backing file for the volume. It must contain a path property pointing to the base volume and a format property defining the format of the base volume.

The base volume format will not be guessed for security reasons and is thus mandatory.
nocow -- disable COW for the volume.
connection -- libvirt connection URI, overriding defaults
username -- username to connect with, overriding defaults
password -- password to connect with, overriding defaults

CLI Example:

Volume on ESX:

salt '*' virt.volume_define "[local-storage]" myvm/myvm.vmdk vmdk 8192

QCow2 volume with backing file:

salt '*' virt.volume_define default myvm.qcow2 qcow2 8192                             permissions="{'mode': '0775', 'owner': '123', 'group': '345'"}"                             backing_store="{'path': '/path/to/base.img', 'format': 'raw'}"                             nocow=True

New in version 3001.
