It certainly should be possible. I've only ever had Xen VMs running GFS but I can't think of any reason why you shouldn't run it on the host too. One thing you should ensure though, is that the cluster can continue to work with just the host running. To do this you could either (with cman) give the host more votes than the sum of the VMs votes or (with gulm) put a single gulm server on the host. There may be memory constraints with the latter arrangement of the lock traffic is high though. > If possible has anyonegot a howto? > I have a more general document on Fedora/Xen at http://www.cix.co.uk/~tykepenguin/xencluster.html , it doesn't cover exactly what you need and it's not really a HOWTO, but it might help! -- patrick
