The guest read or wrote a model specific register which kvm does not implement.
It's looked with sufficiently high priority to get spewed onto the console.
It's done so if the problem is the cause of a guest malfunction, we'll have a clue.

Of things written to syslog before the freeze occurs so that they don't reach the disk reliably? I could set up logging (which facility/priority?) to the serial console.
