[libvirt] Update on host interface configuration

[Dan Kenigsberg]

I know I'm arriving very late to this discussion and should have read
it all before posting, but...

The project I'm working on wanted to be able to setup network
configuration without making persistant changes to configuration files.
This would allow testing if everything works well, and reboot without
fear if things got broken. The greatest fear when configuring network
remotely, is being locked out of your host.

Do you plan something like this feature in netcf?

Dan.
