Subject: [Qemu-devel] [RFC PATCH v2 08/17] fuzz: Export the qemu_savevm_live_state function
Date: Mon, 5 Aug 2019 07:11:09 +0000 [thread overview]
Message-ID: <20190805071038.32146-9-alxndr@bu.edu> (raw)
In-Reply-To: <20190805071038.32146-1-alxndr@bu.edu>
Skip the header when saving device state, as the header isn't handled by
qemu_load_device_state
Signed-off-by: Alexander Oleinik <alxndr@bu.edu>
