pvpanic device is an internal default device in qemu. It may cause
problem when upgrading qemu from a version without pvpanic.
for example: in Windows(let's say XP) the Device manager will open a
"new device" wizard and the device will appear as an unrecognized
device. On a cluster with hundreds of such VMs, If that cluster has
a health monitoring service it may show all the VMs in a "not healthy"
state.
This patch is a workaround to not show pvpanic in UI to avoid the
problem in Windows.
