Overview

Puppet module to install libvirt and create virtual domain configuration. This module has very minimal external dependencies and tries to not make any assumptions about how you want to setup your virtual machines.

The module contains helper scripts to manage VMs on a 2 node cluster with disk replication over DRBD. But this is completely optional.

Description

This module tries to adhere to the Unix philosophy of doing one thing but doing it right. It installs and configures libvirt and virtual domains, but does not do the basic setup of your networking bridge or configure the disks used by the virtual domains. This is left to other puppet modules.

For a basic setup you have to include the libvirt class, define a libvirt::network and a libvirt::domain.

As an optional add-on this module contains a libvirt hook and a Python management script to create a 2 node cluster with disks replicated over DRBD. This setup allows live migration of VMs from one node to the other.

A complete working solution can be achived by integrating the following modules in addition to this module:

Usage

Install libvirt:

class {'libvirt': }

Install including the DRBD hook:

class {'libvirt':
  qemu_hook => 'drbd',
}

Define a network (basic linux bridge example):

libvirt::network { 'net-simple':
    forward_mode   => 'bridge',
    bridge         => 'br-simple',
}

Define a network (advanced openvswitch example):

libvirt::network { 'net-ovs':
  forward_mode     => 'bridge',
  bridge           => 'br-ovs',
  virtualport_type => 'openvswitch',
  autostart        => true,
  portgroups       => [
                       {'name'     => 'intern',
                        'trunk'    => false,
                        'vlan_tag' => '2',
                        },
                       {'name'     => 'trunk',
                        'trunk'    => true,
                        'vlan_tag' => ['100', '101', '102', ],
                        },
                       ],
}

Define a domain (VM):

libvirt::domain { 'my-domain':
  max_memory     => '2000',
  cpus           => 2,
  boot           => 'hd',
  disks          => [{'type' => 'block',
                      'device' => 'disk',
                      'source' => {'dev' => '/dev/vm-pool/my-domain.img'},
                      },
                     {'type'   => 'file',
                      'device' => 'disk',
                      'source' => {'dev' => '/var/lib/libvirt/images/my-disk.qcow2'},
                      'bus'    => 'virtio',
                      'driver' => {'name'  => 'qemu',
                                   'type'  => 'qcow2',
                                   'cache' => 'none',
                                   },
                     ],
  interfaces     => [{'network' => 'net-simple'},],
  autostart      => true,
}

Complete documentation is included in puppet doc format in the manifest files.

Reference

Functions

libvirt_generate_mac

Returns a MAC address in the QEMU/KVM MAC OID (52:54:00:...)

libvirt_generate_mac_addresses

Generates MAC addresses for all interfaces in the array which do not yet have an address specified. The MAC addresses are based on the domain name, network and portgroup.

Limitations

Things currently not supported:

  • Operating Systems other than Debian or RedHat. Adding support for other systems is a matter of defining the relevant parameters in params.pp. So this is really easy for someone with access to such a system.
  • libvirt storage pools
  • Network interfaces not attached to a libvirt network

Patches to support any of these (or other) missing features are welcome.
