[SOLVED] Networking Broken after failed FC17-18 Upgrade

I had a fedup based upgrade from F17 to F18 fail on me and leave a load of duplicate RPMs. After unpicking this with, my network setup is rather broken, and in it's current state does not provide me with default route, making reaching the box rather tricky. With various combinations of ifup and ifdown I can sometimes reach the box, but this obviously does not survive a reboot. As the box was being used as an oVirt server, I have an ovirtmgmt bridge running on em1, plus a further 3 interfaces as em2-4. I'm rather stumped and hoping for some ideas.

I also have problems with ovirt not being able to connect to the Postgres server, but first things first...

Forget that. I've got it working by not having multiple interfaces with DEFROUTE=yes. Which I thought I'd already tried. :-S
