In my experience, you need a checkpoint from an N cpu system to restore in an N cpu system. That is, the checkpoint contents depend on the number of cpus and are not interchangeable. If I'm wrong about this, I would be happy to be corrected!
PS: One reason this is true is that the checkpointed OS has information in it about the number of cpus, what is scheduled where, etc. All of this information is in the memory state that is part of the checkpoint. Restoring from a checkpoint is definitely not the same as an OS reboot, which detects the number of cpus and builds OS tables accordingly.
