Spot on! The script qemu-ifup was indeed the cause of the problem. It's a dummy script that only does "exit 0" and it was apparently needed in the past with old versions of libvirt.
Only if you previously used interfaces of type='ethernet' that required some external action when the interface was started.
I see examples on the net where it is used to configure interfaces with shell commands. I don't need it.
I see that everything works fine without the <script path="/opt/oa/etc/qemu-ifup"/> line, for vhostuser and ethernet interfaces. Are there any side effects or can I safely remove that line?
Since that line is causing an error when you try to start the domain (since it is not supported or allowed for type='vhost-user', nor has it *ever* been supported as far as I know), definitely remove the <script> line from your config.
