I very well appreciate your help with this. no offense, but the Xen
support for libvirt is pretty basic as it is... imho, it would help if Xen
developers help a bit with the libvirtd XEN driver, and i talked to Citrix
people about this, not sure if it'll work out, but we'll see...

As the Xen package maintainer for Mageia, i would like if libvirt would be
better supported on Xen.

In any case, we are already in version freeze for the coming Mageia 3
release and release freeze is coming soon, it would be awesome if i could
add this patch so that Mageia 3 would have working XEN dom0 + libvirtd

Kind Regards,


PS: testing 1.0.4 showed a new bug: if i use the reboot command from the
HVM guest, virt-manager seems to stop refreshing the cpu graph and the
guest doesn't actually seem to reboot (the vnc window can't connect
either). i have to force shutdown it (crashing libvirtd) and booting it up
