Subject: [Qemu-devel] [PATCH 3/3] replay: disable default snapshot for record/replay
Date: Tue, 31 Jan 2017 14:57:45 +0300	[thread overview]
Message-ID: <20170131115745.5244.36762.stgit@PASHA-ISP> (raw)
In-Reply-To: <20170131115728.5244.21690.stgit@PASHA-ISP>

This patch disables setting '-snapshot' option on by default
in record/replay mode. This is needed for creating vmstates in record
and replay modes.
