Long story short, this is mostly due to virbr0 bridge access with the 
regular user. I didn't know about the qemu bridge helper, so I ended up 
marking the libvirt tests as 'root only'. I'll fix this ASAP.

Yes, we have an extensive set of qemu tests. By default we run basic 
qemu migration tests, but there are many others, it's all a matter of 
running:

./run -t qemu --list-tests

To see what's in there.

Speaking of migration tests, I recall talking about this before with 
Daniel, but long story short, I believe it would be beneficial for 
libvirt to implement migration inside the same host. With qemu is 
possible to do that, qemu transfers its state to another qemu process. 
It is very handy to test migration, and it seems doable in libvirt as well.

Thanks,
