[libvirt] Libvirt support for windows

Hi, I want to use libvirt for windows but when i try to launch virsh it gives an error message saying "*error: invalid argument in transport methods unix, ssh and ext are not supported under Windows"* The version which I downloaded is libvirt-0.8.8.exe. I want to connect to two virtualization techniques --- *Virtualbox* and *VMWare* If libvirt is not supported on windows then is there any other tool or API which supports multiple virtualization technology? Thanks in advance..!!!!
