I enabled debugging and it looks like it doesn't support the multiport
extension:
viocon0 at virtio5 -MultiPort -EmergWrite +RingIndirectDesc -RingEventIdx +Version1
I haven't been able to get it to work, not sure if that's why.
Originally qemu had a "virtio-console" device that only supported a
single port, then it was enhanced to be called "virtio-serial" and
supported multiple ports per device:

I feel like there's a mismatch between the driver and the newer virtual
serial port hardware, but this level of driver operation isn't my usual
forte so I can't say for sure.
From my perspective, it would be great if somebody updated it :), but
enabling it as it is doesn't seem a good idea as it doesn't appear to
work 8-/.
It looks like the FreeBSD virtio_console driver supports the current
multiport virtio-serial device and works with qemu and the qemu guest
agent. The code is somewhat similar but also drastically different ;).
Thanks for the reply...
