What version of the virtio-win drivers are you using? More specifically,
what's the name of the ISO/package you used? I'm not sure how
"Driver Date" maps to actual virto-win releases.

There is a test utility on the virtio-win ISO called "vioser-test.exe".
I'd recommend running that to confirm whether or not it's a qemu-ga
issue. Before you run it, attach something to the host-side socket to
confirm you get the expected output from the test utility, such as
`nc -U /tmp/qemu-ga.w2008.0.sock`

Also, any logs/output from the QEMU process may provide some
clues as well.
