Hello Steve:

According to you bisect result, maybe the issue of the event index in qemu.

Looks like you didn't use vhost according to your qemu-kvm cli, could you
please try to see whether the 3.3-rc6 guest works under vhost backend (-netdev
tap,vhost=on,id=XXX -device virtio-net-pci,netdev=XXX ... ). And if it works,
could you please then try 3.3-rc6 guest without vhost and disable event index
feature by -device virtio-net-pci,event_idx=off ?

thanks
