Dump: add qmp command "query-dump"
When dump-guest-memory is requested with detach flag, after its return, user could query its status using "query-dump" command (with no argument). The result contains: - status: current dump status - completed: bytes written in the latest dump - total: bytes to write in the latest dump From completed and total, we could know how much work finished by calculating: 100.0 * completed / total (%) Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <1455772616-8668-10-git-send-email-peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
