Table 2 Factors impacting the metrics

From: A critical survey of live virtual machine migration techniques

Performance metrics Factors
Downtime Synchronization mechanism, low-bandwidth network
Amount of transferred data It may be larger than the actual run time data size because there must be some redundancy for Synchronization and protocol
Total migration time Large amount of data (some pages need to be transferred multiple times because of modification)
