It's certainly possible the hangs you're seeing were caused by the
IOAPIC interrupt injection bug I just sent out a fix for - you could try
doing an install either running kvm-qemu -no-kvm-irqchip or booting the
guest with "noapic" on the kernel command line. If the IOAPIC bug is
your issue, you shouldn't see any freezes.

Cheers,
Mark.
