Comment 3 Vadim Rozenfeld 2014-02-04 07:08:42 UTC 
there were some critical bug fixes since virtio-win-prewhql-68.
Can we please retest with the most recent drivers from build-74?

Thanks,
Vadim.
Comment 4 Ronen Hod 2014-03-25 10:42:13 UTC 
QE, Please retest with the latest build (at least 74).
Please inject NMI when the guest is stack once again.

Thanks.
