No, the Windows support we are targetting is client-mode only. ie, allow
use of libvirt clients to connect to remote Linux hosts running libvirtd.

If someone wants to implement a libvirt driver for Hyper-V patches are 
of course welcome, but its not a high priority for any of the developers
I know.

Again we'd like to have someone contribute patches to support VMWare
management. Quite a few people have expressed interest in this, but no
one yet wrote much if any code.
