The kludge around for now is to disable mpbios in OpenBSD.
In theory you can do it with the boot time kernel configuration.
For at least one iteration of QEMU/KVM I had to build a custom
OpenBSD kernel for that to actually work.

However, if any KVM folks would like a guinea pig to take dumps
and traces to figure out where OpenBSD isn't playing nice with
QEMU/KVM, I'll volunteer.
