I tested with both virtio-win-0.1-22.iso and virtio-win-0.1-30.iso.

Running vioser-test.exe reports error 5.
"Running in non-blocking mode.
Cannot find vioserial device \\?\{6FDE7547-1B65-48AE-B628-80BE62016026}#VIOSERIALPORT#4&263E99FC&0&01#{6FDE7547-1B65-48AE-B628-80BE62016026}, error = 5

Before you run it, attach something to the host-side socket to

echo "{'execute':'guest-ping'}" | socat stdio unix-connect:/tmp/qemu-ga.w2008.0
-- no response.. I tried this with another linux server which has guest agent loaded and get the same no response.

Checked the logs and found nothing abnormal which is reported, following is the process list.
