[libvirt-users] Windows guest and virtio serial port

[Tadas]

Okay, I've updated virtio serial drivers to latest ones. This did not
help. Afterwards I've enabled "Show hidden devices" in Device manager
of a guest os.In the "Other devices" section I can see two virtio serial ports with
question marks (i did configure guest with 2 virtio channels).
Is this a normal behaviour?

Any ideas would be appreciated. Thank you.
