With fullvirt yes. With paravirt + FC6 no. With paravirt + F7 yes.


FYI, while the plan for Fedora 7 called for Xen 3.0.4, we have belatedly
switched to 3.1.0 since it is in final release-candidate phase & has lots
of very important bugfixes we wanted. This has the added benefit of letting
you run 32-bit PV guests on 64-bit host, although this should be considered
fairly cutting edge / experimental :-)
