Re: [libvirt] [PATCH 6/6] Implement migration v3 protocol in QEMU driver

Implement the v3 migration protocol, which has two extra steps, 'begin' on the source host and 'confirm' on the source host. All other methods also gain both input and output cookies to allow bi-directional data passing at all stages * src/qemu/qemu_driver.c: Wire up migrate v3 APIs * src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Add begin & confirm methods --- src/qemu/qemu_driver.c | 318 +++++++++++++++++++++++++++++++++++++++++++- src/qemu/qemu_migration.c | 141 ++++++++++++++++++-- src/qemu/qemu_migration.h | 16 ++-
