I have CCed Vadim (virtio Windows driver) and the QEMU mailing list.

Please post your QEMU command-line so we can see how the guest is configured.

You mentioned that you debugged the driver and hardware resources
weren't allocated.  Do you have a virtio PCI device inside the guest
for this virtio-serial device?  Were you able to tell which part of
driver initialization failed (finding the PCI device, mapping its
resources (BARs), etc)?
