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. Cc: Marcel Apfelbaum <[email protected]> Cc: "Michael S.
