lguest: Allow running under paravirt-enabled KVM.
We actually can run under KVM, as it doesn't paravirtualize anything we need to use; reduce the check to checking we are the normal ringlevel. Reported-by: Stefanos Geraggelos <sgerag@cslab.ece.ntua.gr> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au># HG changeset patch
