It turns out everything was booting, they just weren't configured to give a console or display a GUI window. -matthew

I've been having trouble getting a Xen HVM guest started using libvirt. I've tried Windows Vista, Fedora Core 8, and Fedora Core 6 guests. Domain 0 is FC 8. The only guest that starts correctly is the FC 6 guest. Has anyone else encountered something like this? Is there a master list of guest OS's that libvirt supports?

Thanks -matthew
