Hi Vadim.

Thank you kindly for getting back to me.

I can certainly do that:

Dump and BSOD are in a zip at
http://dl.dropbox.com/u/12332019/2200-VirtioBSOD-2.zip

This time running with 2 cores:

qemu-kvm -m 1024 -smp sockets=1,cores=2 -cpu host -nodefaults -vga cirrus
-vnc :1  -drive if=none,id=block.0,format=raw,
cache=writeback,file=drive.img -device
virtio-blk-pci,bootindex=1,drive=block.0 -monitor stdio

Same procedure to get it to break - run crystal disk mark. Passed the
stream read/write and 512k block read/write - broke at the seek intensive
4k level.

Regards,
Paul
