I learned some new things about virtio-serial that are worth
mentioning.
First, the configuration I am using with some F12 guests is not true
virtio-serial. Rather, it is just serial port emulation in the guest
which maps to a UNIX socket on the host. This is how fence-virtd
works, but it is my understanding that we do not want to go this
route. By using the virtio-serial, the device created in the guest
will not be a true serial device (as in fence-virtd). Rather, we'll
have a plain character device for communication. This should be much
more simple.
To get true virtio-serial support, we'll need F13. I'm currently
working on getting F13 beta installed and some VMs created.
In the meantime, we should being looking at implementing heartbeat
over QMF. Darryl, do you have time to discuss this? Perhaps we should
schedule a call to hammer-out some details and then post our thoughts
to the list.
