Hello Michael,
Thank you very much for pointing to the virtio driver package for windows. It does have the vioser-test utility.

I'm not familiar with this vioser_test utility, is it part of the virtio
driver package for windows? If so the source code is available here:

http://git.kernel.org/?p=virt/kvm/kvm-guest-drivers-windows.git

Amit's virtio-serial test suite is also available for reference:

http://fedoraproject.org/wiki/Features/VirtioSerial#How_To_Test

I'm not sure how applicable it is for windows though.
