Work with virtual machines managed by libvirt

  • libvirt Python module

  • libvirt client

  • qemu-img

  • grep

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:

Units specification

New in version 3002.

The string should contain a number optionally followed by a unit. The number may have a decimal fraction. If the unit is not given then MiB are set by default. Units can optionally be given in IEC style (such as MiB), although the standard single letter style (such as M) is more convenient.

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 --

    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'

    }
    
    source_auth={
        'type': 'chap',
        '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)

  • connection -- libvirt connection URI, overriding defaults

  • username -- username to connect with, overriding defaults

  • password -- password to connect with, overriding defaults

Permissions definition

The permissions are described by a dictionary containing the following keys:

mode

owner

the numeric user ID of the owner. (Default: from the parent folder)

group

the numeric ID of the group. (Default: from the parent folder)

label

    Refer to Boot parameters definition for the complete boot parameter description.

    To update any boot parameters, specify the new path for each. To remove any boot parameters, pass None object, for instance: 'kernel': None. To switch back to BIOS boot, specify ('loader': None and 'nvram': None) or 'efi': False. Please note that None is mapped to null in sls file, pass null in sls file instead.

The definition used in the dictionary can be found at cpu parameters definition.

    To update any numatune parameters, specify the new value. To remove any numatune parameters, pass a None object, for instance: 'numatune': None. Please note that None is mapped to null in sls file, pass null in sls file instead.
