On the Ubuntu 'Trusty' guest this problem has still gone away, but it's still there with the 'Saucy' guest; Trusty has just had an X and spice update - so looking at that last trace I posted I wonder if the problem is X stopping the first chvt from working and then once in that state further chvt's breaking things?
(I guess it going away is a good thing - but if the kernel oops was still triggerable with a bad X server I guess that's still a problem)
