This happens randomly, more often than not the next xm create will
succeed. Don''t think kernel config is related as I use almost identical
setup on my UP machine, but I use the work around for dev designations
on all the vm configs. With that setup I get 100% success on creation of
domU''s with changeset: 7353:29db5bded574, this changeset would not boot
dom0 on the SMP machine.
Tyan 2462 SMP , FC4 dom0
