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.
