Please don't top post.

Not sure what's going wrong here. Maybe the MOL patchery to circumvent 
split real mode doesn't work? Maybe there's something not working with 
the dcbz32 patchery?

You could try to trace the guest through /sys/kernel/debug/tracing and 
see where it's stuck. You can also tell XNU to be more verbose by 
passing in a debug= parameter - though I don't remember the exact syntax 
anymore.

SMP should be fine. The reason XNU doesn't work with QEMU + KVM is split 
real mode. We don't emulate that one properly in KVM yet.
