[fedora-virt] Virtio-win Windows NIC goes offlineduringbulkcopies

[Greg Scott]

I can also tentatively report better results. I put in a gb switch at
the colo site connecting the servers I had here at my place before.  So
now I have the exact same hardware that gave me trouble before.  I just
finished a 100GB backup from a Win2003 physical server to a Win2008R2 VM
using that new preWHQL driver in the 2008R2 VM and it ran to completion
in 5 hours and 8 minutes.  I am starting up one more test that will
backup around 175 GB.  I will report results here when it finishes a few
hours from now.

We experienced a similar problem, while copying a bulk of data to
several VMs (Windows 2008 / 64 Bit). I was able to recreate this
problem, anytime.

So far, I'm unable to recreate the problem with the preWHQL drivers
provided by Vadim. It looks good from my point ot view, now!
