qemu: Transfer migration statistics to destination
When migrating a transient domain or with VIR_MIGRATE_UNDEFINE_SOURCE flag, the domain may disappear from source host. And so will migration statistics associated with the domain. We need to transfer the statistics at the end of a migration so that they can be queried at the destination host. Signed-off-by: Jiri Denemark <jdenemar@redhat.com>
