This means that qemu said "I've finished with buffer 64" and the guest didn't
know anything about buffer 64.

We should not lock up, tho networking is toast: I think that qemu got upset
and that caused this as well as it to chew 100% cpu.

I'll see if I can reproduce with kvm-84 userspace and 2.6.27 guests, 32-bit
guests on a 64-bit AMD host.  What's your kvm/qemu command line?

I've hit this as well.

Intel host, running RHEL5.3, x86_64 with KVM-81.

Guest is RHEL4.7, 32-bit, with the virtio drivers from RHEL4.8 beta.

Happens pretty darn quickly for me.

Like I said, pretty darn quickly.

Can you reproduce it also with e1000 instead of virtio?
