Puppet Virtualization Management Module

Puppet Module to manage virtual machines using libvirt.

Overview

This module provides a new type (virt) for virtual machines installation and management like ensure running and so on. All the operations will be made using libvirt [0]. At first, only Xen fullyvirtualisation, Xen paravirtualisation and KVM will be supported.

This module is the result of my work at GSoC 2010.

Usage

This is the full specification for the new types. All have the same fields:

virt { "name":
    desc            => "My first VM",
# Basic configuration
    memory          => 1024, # MB, changeable
    cpus            => 2, # Changeable
    arch            => x86_64 | i386,
    clocksync       => UTC | localtime | timezone | variable, # Clock source

# Boot configuration
    boot_localtion  => "/path/to/vmlinuz and initrd.img",
    boot_options    => "ks=foo noacpi" # Non changeable, controls, kickstart
        #For now, only the existing .img, .qcow2 and .qcow  files will be supported
    virt_path       => "/path/foo.img" | "/opt/virt_images/" | "/dev/sd4"

# Storage configuration
    disk_size       => 100000, # MB, not changeable

# OS specification
    os_type         => linux | other | solaris | unix | windows,
    os_variant      => solaris | debian | ubuntu | ...,  # The OS distribution (there's 37 types)

# Virtualization parameters
    virt_type       => kvm | xen-fullyvirt | xen-paravirt  # for libvirt provider, this field is mandatory

# Network configuration
    interfaces      => [ "eth0", "eth1" ] | "disable" # Source host interface. Default eth0 or the existing interface

# VM behaviour
    autoboot        => true | false,
    ensure          => running | stopped | installed | absent, # Default value: running
    on_poweroff     => destroy | restart | preserv | rename-restart  # Default value: destroy
    on_reboot       => destroy | restart | preserv | rename-restart
    on_crash        => destroy | restart | preserv | rename-restart
}

Future Work

For now, some parameters will have a few values acceptable:

• virtpath will accept only existing .img, .qcow and .qcow2 files;
• memory and cpus will be, initially, not changeable;
• input devices specification like mouse and graphic will not be supported for now.
