Subject: [Qemu-devel] [PATCH 0/2 v3] kvm: notify host when guest panicked
Date: Thu, 08 Mar 2012 15:57:01 +0800 [thread overview]
Message-ID: <4F58664D.1070800@cn.fujitsu.com> (raw)
We can know the guest is paniced when the guest runs on xen.
But we do not have such feature on kvm.
Another purpose of this feature is: management app(for example:
libvirt) can do auto dump when the guest is crashed. If management
app does not do auto dump, the guest's user can do dump by hand if
he sees the guest is paniced.
I touch the hypervisor instead of using virtio-serial, because
1. it is simple
2. the virtio-serial is an optional device, and the guest may
not have such device.
Changes from v2 to v3:
1. correct spelling
Changes from v1 to v2:
1. split up host and guest-side changes
2. introduce new request flag to avoid changing return values.
