[Qemu-devel] [PATCH] ipmi: Add graceful shutdown handling to the external BMC

[minyard]

From: Corey Minyard <address@hidden>

I misunderstood the workings of the power settings, the power off
is a force off operation and there needs to be a separate graceful
shutdown operation.  So replace the force off operation with a
graceful shutdown.

This is the final patch to implement proper shutdown for the
external interface.  OpenIPMI is changed to match this.
