[libvirt] Support for Parallels products?

Hi all, Has anyone looked at adding support for Parallels virtualisation products, or have any idea if it's even possible? Google isn't showing much in the way of search results, so not sure it's been looked at before. These are the server oriented products: http://www.parallels.com/au/products/server/ They have a hosted hypervisor (like VMware GSX/Server), and a bare metal hypervisor. They also have desktop oriented products: http://www.parallels.com/au/computing/
