Subject[PATCH v12 rebased 0/8] pv event to notify host when the guest is panicked
Date
This series implements a new interface, kvm pv event, to notify host when
some events happen in guest. Right now there is one supported event: guest
panic.

Also, the cpu runstate is preserved during save/load vm and migration. Thus,
if vm is panicked during migration, we can still know it by quring the status
of vm in destination host.

This version is a rebase and no code change.
