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 fullyvirtualization, Xen paravirtualization, KVM and OpenVZ are 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            => "i386" | "i686" | "amd64" | "ia64" | "powerpc" | "hppa"
    graphics        => enable | disable | vnc:VNCPORT
    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       => 10, # GB, not changeable

# OS specification
    os_type         => linux | other | solaris | unix | windows | hvm,
    os_variant      => solaris | debian | ubuntu | ...,  # The OS distribution (there's 37 types)
    tmpl_cache      => "debian-5.0-i386-minimal" | "fedora-13-x86_64" | ...,  # This only applies to OpenVZ guests

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

    * If you specify openvz as a type you'd like to create, the following fields
      are the minimum requirements: `name`, `memory`, `vcpu`, `tmpl_cache`, and `xml_file` *

# Network configuration
    interfaces      => [ "eth0", "eth1" ] | "disable" # Source host 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

# XML configuration
    # This will allow you to create a new guest from an already defined XML configuration file.
    xml_file        => "/etc/libvirt/qemu/name.xml"

    * When creating a new openvz container this option is required - note
      please that the xml file must be named after the VEID i.e. (/etc/libvirt/qemu/101.xml) *
}

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.
• The parameters on_poweroff; on_reboot and on_crash are not changeable. They will be used only to create a new domain (not for import existing domain's image, because libvirt does not support modify those values)
• if virt_type is openvz, providing both tmpl_cache and xml_file are required.
