[Qemu-devel] [PATCH v2 1/4] vl: add qemu_system_shutdown_force() |
Date: |
Fri, 25 Jul 2014 14:16:43 +0100 |
The QEMU --no-shutdown option prevents guests from shutting down. There
are several cases where shutdown should be forced, even if --no-shutdown
was given.
This patch adds an API for forcing shutdown. This cleans up the code
and hides the extern int no_shutdown variable which is currently being
touched in various files.
