[Libvir] can't start windows guest domains

[Thomas Antony]

Hi.

I'm running F7 x86_64 with kernel 2.6.20-2931.fc7xen and 
libvirt-0.3.2-1.fc7. Since i updated to the latest versions i can't 
start any windows domains anymore. I thought undefine and reinstall the 
domains could resolve the problem, but i get the exact same error message.
There is also a F7 x86_64 guest domain runnning fine on the same host.
Why i can't start any windows domains anymore?

Disk /dev/VolGroup01/sbs is already in use by another guest!  Do you 
really want to use the disk (yes or no)?  y
