Can you check if -global apic.vapic=off makes any difference in the
broken case? I'm facing general issues in that setup once I enable
virtio-block - independent of vapic on/off or in-kernel/userspace. The
boot freezes, and qemu can only be terminated via kill -9. So, retrying
with IDE as block interface would also be interesting.
