Changes from V1: - Use ELF dumps produced by the dump-guest-memory command; - Use checkpoints for all memory blocks; - Use trace_ instead of DPRINTF; - removed RAM_SAVE_FLAG_PAGE_HASH flag; - General code cleanup and update to latest QEMU codebase.
This patchset contains a checkpoint-assisted migration feature as proposed earlier on this list [1]. It allows reusing existing memory snapshots of guests to speed up migration of VMs between physical hosts.
