But then, you can just sever the replication link and end up with a "free" unchanging image on the Secondary. Don't let your primary crash at that time, though - snapshots should add more safety. > I looked at http://www.drbd.org/users-guide/s-xen-configure-domu.html , > but this seems to exclude HVM guests. I think it's a good option to have Xen use the DRBDs as plain block devices, i.e., Xen doesn't need to be aware of DRBD. I believe I read on this list that live migration is quite possible so long as both nodes become primary on time. HTH, Felix
