Subject: [Qemu-devel] [PATCH v11 7/8] qemu.py: launch vm only if it's not running
Date: Tue, 14 Nov 2017 11:22:45 +0100	[thread overview]
Message-ID: <20171114102246.22221-8-apahim@redhat.com> (raw)
In-Reply-To: <20171114102246.22221-1-apahim@redhat.com>

If we allow launching VM again we will loose track of the first launched
VM.
