We already have this in libvirt. See virDomainParseXMLIfDesc()
Ahh I missed that. I will have to write some tests for that I think,
although it'll require extending the test:///default driver to support
the networking APIs :-)

I'm not sure why you want this?
Without this you be sending in
<interface type='network'>
<source network='foo'>
</interface>
And be getting back
<interface type='bridge'>
<source bridge='virbr0'>
</interface>
As far as is possible the XML used to create a VM should be identical
to that you get back from libvirt once it is running.

Yes, we should definitely have this.
Ok, I'll add that - it should be trivial since the tricky enslaving
code is already there.
