salt.modules.virt

Work with virtual machines managed by libvirt

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 Fluorine.

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.

The calls not using the libvirt connection setup are:

  • seed_non_shared_migrate
  • virt_type
  • is_*hyper
  • all migration functions

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:

disk_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 libvirt 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)

Graphics Definition

The graphics dictionnary can have the following properties:

type

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

See the libvirt 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.

  • name -- libvirt storage pool name
  • connection -- libvirt connection URI, overriding defaults
  • username -- username to connect with, overriding defaults
  • password -- password to connect with, overriding defaults

New in version Fluorine.

CLI Example:

salt '*' virt.pool_build default
salt.modules.virt.pool_define(name, ptype, target=None, permissions=None, source_devices=None, source_dir=None, source_adapter=None, source_hosts=None, source_auth=None, source_name=None, source_format=None, transient=False, start=True, **kwargs)

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 pool-define-permissions 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 informations on the use of part_separator

  • source_dir -- Path to the source directory for pools of type dir, netfs or gluster. (Default: None)
  • 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',
            'uuid': '2ec115d7-3a88-3ceb-bc12-0ac909a6fd87'
        }
    }
    
    source_auth={
        'type': 'chap',
        'username': 'myname',
        'secret': {
            'type': 'usage',
            'uuid': 'mycluster_myname'
        }
    }
    
  • 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

Permissions definition

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

mode
The octal representation of the permissions. (Default: 0711)
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
the SELinux label. (Default: None)

CLI Example:

Local folder pool:

salt '*' virt.pool_define somepool dir target=/srv/mypool                                   permissions="{'mode': '0744' 'ower': 107, 'group': 107 }"

CIFS backed pool:

salt '*' virt.pool_define myshare netfs source_format=cifs                                   source_dir=samba_share source_hosts="['example.com']" target=/mnt/cifs
