BSOD on plug&play searched because of lost harddrive on virtio scsi controller

[Patrick Vorlicek <patrick.vorlicek@udo.edu>]

Hello,

I have a problem with mit my Windows 7 x64 / Windows Server 2008 R2 
guest on a Ubuntu Server (Kernel 3.11.0-rc2) Host with two Intel Xeon CPUs.

Both guests have the RedHat VirtIO drivers for the disk and network 
adapter installed. I tried version 1.65 from 
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ but also version 
1.59.

Everytime I hotadd a disk or just search for new devices in the device 
manager, the system (or even all discs) get lost resulting in a BSOD 
with CRITICAL_OBJECT_TERMINATION (0x000000f4 stop code) after some kind 
of timeout. I couldn't find any documentation of a simular issue, so I'm 
asking here for help.

The xml-description of the virtual machine - i'm using libvirt - looks 
like this:

I hope that's all information needed. Except this issue everything works 
fine and stable with these virtual machines.
