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:///

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

Network Interface Definitions

Network interfaces dictionaries can contain the following properties:

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)

Disk 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)

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)

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)

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
          pool: zroot/bhyve/guests
      - data:
          pool: tank/disks
          size: 20G
          hostname_property: virt:hostname
          sparse_volume: True

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.

device

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

Graphics Definition

The graphics dictionnary 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.

Loader Definition

The loader dictionary must have the following property:

path: Path to the UEFI firmware binary

Optionally, you can provide arbitrary attributes such as readonly or type. See the libvirt documentation for all supported loader parameters.

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
