From fe025508c0c98ff1349c02e6f99b13844d7079b1 Mon Sep 17 00:00:00 2001 From: Mao Zhongyi Date: Wed, 3 Jun 2020 16:08:59 +0800 Subject: [PATCH] monitor/hmp-cmds: don't silently output when running 'migrate_set_downtime' fails Although 'migrate_set_downtime' has been deprecated and replaced with 'migrate_set_parameter downtime_limit', it has not been completely eliminated, possibly due to compatibility with older versions. I think as long as this old parameter is running, we should report appropriate message when something goes wrong, not be silent. before: (qemu) migrate_set_downtime -1 (qemu) after: (qemu) migrate_set_downtime -1 Error: Parameter 'downtime_limit' expects an integer in the range of 0 to 2000 seconds Signed-off-by: Mao Zhongyi Reviewed-by: Dr. David Alan Gilbert Message-Id: <20200603080904.997083-5-maozhongyi@cmss.chinamobile.com> Signed-off-by: Dr. David Alan Gilbert --- monitor/hmp-cmds.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/monitor/hmp-cmds.c b/monitor/hmp-cmds.c index 2c630ec88d..a704b3469a 100644 --- a/monitor/hmp-cmds.c +++ b/monitor/hmp-cmds.c @@ -1189,8 +1189,11 @@ void hmp_migrate_pause(Monitor *mon, const QDict *qdict) /* Kept for backwards compatibility */ void hmp_migrate_set_downtime(Monitor *mon, const QDict *qdict) { + Error *err = NULL; + double value = qdict_get_double(qdict, "value"); - qmp_migrate_set_downtime(value, NULL); + qmp_migrate_set_downtime(value, &err); + hmp_handle_error(mon, err); } void hmp_migrate_set_cache_size(Monitor *mon, const QDict *qdict) -- 2.11.4.GIT
