From 39ba2ea61f510512764e6f9063a8396d05fe57fe Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Thu, 18 Feb 2016 13:16:54 +0800 Subject: 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 Signed-off-by: Peter Xu Message-Id: <1455772616-8668-10-git-send-email-peterx@redhat.com> Signed-off-by: Paolo Bonzini --- qmp-commands.hx | 27 ++++++++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) (limited to 'qmp-commands.hx') diff --git a/qmp-commands.hx b/qmp-commands.hx index d30b1eb..daaafe5 100644 --- a/qmp-commands.hx +++ b/qmp-commands.hx @@ -856,7 +856,8 @@ Arguments: - "protocol": destination file(started with "file:") or destination file descriptor (started with "fd:") (json-string) - "detach": if specified, command will return immediately, without waiting - for the dump to finish (json-bool) + for the dump to finish.
