Subject: [PATCH] libxl: do not start qemu in dom0 if possible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After previous patch, the only trigger for dom0 qemu is number of
consoles. So if no additional serial console is defined, drop
save/restore stubdom channels as a price for no qemu in dom0.
