Did you install kvm?

If you need to move the xen virtual machines to kvm you will need to boot
them in rescue mode, change your modprobe.conf to load the regular scsci and
nic drivers, install a regular kernel, remove the xen console from inittab
and remove console=xvc0 from your /etc/grub.conf and reboot.
