Subject: [PATCH v12 rebased 0/8] pv event to notify host when the guest is panicked
Date: Wed, 23 Jan 2013 15:19:20 +0800 [thread overview]
Message-ID: <cover.1358920534.git.hutao@cn.fujitsu.com> (raw)
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.

Hu Tao (7):
save/load cpu runstate
update kernel headers
add a new runstate: RUN_STATE_GUEST_PANICKED
add a new qevent: QEVENT_GUEST_PANICKED
introduce a new qom device to deal with panicked event
allower the user to disable pv event support
pv event: add document to describe the usage
Wen Congyang (1):
