Modifications since the first version: 1. As George pointed out, signalling the receiver to enable compression logic is done through XC_SAVE_ID_ENABLE_COMPRESSION marker, instead of sending the compression flag as a separate entity. This way, live migration compatibility is maintained with target machines running older versions of xen. 2. Added comments at appropriate places to explain the compression control logic in xc_domain_save/restore. 3. Tended to nitpicks :). shriram
