Rex::Commands::Virtualization - Virtualization module
DESCRIPTION
With this module you can manage your virtualization.
Version <= 1.0: All these functions will not be reported.
All these functions are not idempotent.

EXPORTED FUNCTIONS
vm($action => $name, %option)
This module only exports the vm function. You can manage everything with this function.
EXAMPLES
Creating a Virtual Machine
Create a (VirtualBox) VM named "vm01" with 512 MB ram and 1 cpu. One harddrive, 10 GB in
size beeing a file on disk. With a cdrom as an iso image and a natted network. The
bootorder is set to "dvd".
vm create => "vm01",
storage => [
{
file => "/mnt/data/vbox/vm01.img",
size => "10G",
},
{
file => "/mnt/iso/debian6.iso",
}
],
memory => 512,
type => "Linux26",
cpus => 1,
boot => "dvd";
Create a (KVM) VM named "vm01" with 512 MB ram and 1 cpu. One harddrive, 10 GB in size
beeing a file on disk. With a cdrom as an iso image and a bridged network on the bridge
virbr0. The Bootorder is set to "cdrom".
vm create => "vm01",
boot => "cdrom",
storage => [
{
size => "10G",
file => "/mnt/data/libvirt/images/vm01.img",
},
{
file => "/mnt/data/iso/debian-6.0.2.1-amd64-netinst.iso",
},
];
This is the same as above, but with all options in use.
