Using SuSE's latest xenpreview bits I could migrate a 3GB guest between two machines (6GB and 4GB). With the new bits, a 2GB guest could be migrated off the 6GB machine, but the 4GB machine could not migrate it back. I currently have the VM set to 1.5GB and it ping-pongs fine. Any idea why so much extra memory seems to be required? John Byrne > sanjay kushwaha wrote: > Hi Tim, > Yes.
