This implies the driver isn't installed/working properly and the virtio-serial
device isn't present.

Vadim: any suggestions for debugging?

A linux guest with qemu-ga installed? If that scenario isn't working for you
it's a different issue, but I'd be interested in the output you see when
running qemu-ga in the linux guest as `./qemu-ga -v` (as root) and then sending
the guest-ping command.
