I'm somewhat lost on the reason for these failures, so if you do have
some time on your hands, please give me a hand debugging this! If I'd
had to guess, I'd say it's either an APIC issue and/or guest memory
corruption.
I'd guess memory corruption.
Does running a uniprocessor guest help? What about a uniprocessor

So last night I started several guests with -smp 8 but without network
to see if IO load is causing the problems. All VMs are down, but one
panic log is rather new:

This is right on startup, if I read things right.
I suggest checking if you have the latest BIOS update applied. I've had
bad experiences with un-updated processors.
