Thanks again to David Nicklay for updating his libvirt Virtualization ZenPack.  This version adds hooks for most of the drivers which libvirt itself supports including:

QEMU: /Server/libvirtHost/QEMU
KVM: /Server/libvirtHost/KVM
XEN: /Server/libvirtHost/XEN
VMWare ESX: /Server/libvirtHost/ESX
Linux Containers: /Server/libvirtHost/LXC
User Mode Linux: /Server/libvirtHost/UML
Open VZ: /Server/libvirtHost/OpenVZ
Open Nebula: /Server/libvirtHost/OpenNebula
Virtual Box: /Server/libvirtHost/VirtualBox

The ZenPack as been tested with QEMU, KVM and VMware but needs testing with the other virtualization platforms supported by libvirt.

Thanks David!
