[RFC] pvpanic notifications for non-panic reboot events

[Thomas Weißschuh]

Hi everybody,

the mechanism for a (Linux) guest to signal a regular shutdown event to
QEMU seems fairly architecture specific and dependent on kernel
configuration.

The existing pvpanic protocol [0] could be extended fairly easily to
also cover these events.

Any thoughts?

Thanks,
Thomas
