Chris,
We ran into this a few months ago and didn't want to use the 'Other PV' option
either, so I created a couple of really simple patches to provide a Windows
2008 R2 Virtio OS template. You can apply these these on top of the 4.0 source,
and then recompile the rpms or debs.
Patches are attached.

Subject: Enabling Virtio for Windows guests on KVM
Greetings,
A question came up a couple days ago on the users list about provisioning
Windows VMs with Virtio enabled on KVM:
http://markmail.org/thread/g42vr63dolaa56yv
The workaround mentioned was to set the OS Type to "Other PV". This seems
non-optimal. Is there a better solution? Or is this a bug/enhancement?
Looking around at the source, isGuestPVEnabled() seems to have a hard coded
list of guest OS which will get virtio provisioned by default. No Windows
OS's are in the list, presumably because the virtio drivers don't ship
natively with Windows. Is there some other way to control what type of
virtual NIC and disk controller hardware gets provisioned on a per-VM or
per-template basis?
Regards,
- Chris
