It was crashing with the most basic XML config file. It included no
<cpu> section at all.

Yes, I have a vcpu section, where I have limited it to four of the
eight, and it still crashes.

Oops, yes, meant 8. My point there was, however, that the "cpu cores"
field from /proc/cpuinfo indicates "1", not "4" as it does on the
host, even when I make more than 1 core available to the guest.

Thanks again,
