Can some one clarify the minimum set that should be the same.. while if others like VNC port Or default bridge can be different. (as the target machine may have vnc port already used.) Also, if there are any compatibility checks for migration that needed to be done for predicting successful migration -- KVM version ? Same... similar.. any other way to find if they are 'compatible' ? (As KVM is released frequently) -- Processor same / similar ? Do we have a good compatibility matrix somewhere ? I am assuming that there is nothing specific to KVM but would like to confirm. -- Memory availability : How to compute availability of "enough" memory ? Free physical memory ? Or some weight on available virtual memory/swap ? weave in some knowledge of ballooning details. Any other checks ? Thanks /Jd
