i apply this patch,
but this patch always results in a bug(bug?). a vm always exits with
'2016-10-17T07:33:40.393592Z qemu-kvm: Virtqueue size exceeded', if you suspend
and resume . (please refer to https://wiki.openstack.org/wiki/Kvm-Pause-Suspend
to see the definiton of suspend and resume in openstack). this operation is
very commonly used in openstack. i am not sure if this patch is elegant .
what is your opinion?
