[Qemu-devel] [RFC V2, PATCH 0/2] Checkpoint-assisted migration proposal

[Bohdan Trach <bohdan.trach@mailbox.tu-dresden.de>]

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.
