Subject: [Qemu-devel] [question] savevm/delvm: Is it neccesary to perform bdrv_drain_all before savevm and delvm?
Date: Mon, 20 Oct 2014 21:48:53 +0800 [thread overview]
Message-ID: <201410202148499451733@sangfor.com> (raw)
Hi,
I noticed that bdrv_drain_all is performed in load_vmstate before bdrv_snapshot_goto,
and bdrv_drain_all is performed in qmp_transaction before internal_snapshot_prepare,
so is it also neccesary to perform bdrv_drain_all in savevm and delvm?
Thanks,
Zhang Haoyu
