[Qemu-devel] [PATCH 1/2] xen_console: ignore console disconnect events from console/0 |
Date: |

The first console has a different location compared to other PV devices
(console, rather than device/console/0) and doesn't obey the xenstore
state protocol. We already special case the first console in con_init
and con_initialise, we should also do it in con_disconnect.
