Stefan can you give me some more info on your hardware and migration setup; that stressapptest (which is a really nice find!) really batters the memory and it means the migration isn't converging for me, so I'm curious what your setup is. What CPU have you got? How many cores are you giving each guest? What network technology are you migrating over? Other than xbzrle what else do you have enabled? How long is the migrate taking for you? Thanks, Dave -- Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK
