I'm more interested in seeing what type of corruption is happening; if you've got a test VM that corrupts memory and we can run a program in that vm that writes a known pattern into memory and checks it then see what changed after migration, it might give a clue. But obviously this would only be of any use if run on the VM that actually fails. > I already tried https://code.google.com/p/stressapptest/ while migrating > on a test VM but this works fine. > > I also tried running mysql bench while migrating on a test vm and this > works too ;-( Dave -- Dr. David Alan Gilbert / dgilb...@redhat.com / Manchester, UK
