Hi, The problem with pvpanic being an internal device is that VMs running operating systems without a driver for this device will have problems when qemu will be upgraded (from qemu without this pvpanic).
The outcome may be, 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. Now what will happen 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. My point is that a device that requires a driver that is not "inbox", should not be present by default. One possible solution is to add it manually with -device from command line. Any thoughts? Marcel
