Subject: [PULL 03/15] replay: disable default snapshot for record/replay
Date: Mon, 14 Oct 2019 18:03:37 +0200 [thread overview]
Message-ID: <20191014160343.8211-4-kwolf@redhat.com> (raw)
In-Reply-To: <20191014160343.8211-1-kwolf@redhat.com>
From: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru>
This patch disables setting '-snapshot' option on by default
in record/replay mode. This is needed for creating vmstates in record
and replay modes.
