Comment 121 for bug 997978

I've found this problem in my saucy installation. I just opened a bug cause I'm not sure if it's related.

My problem is actually worse since host machine cannot get access to other machines on the network. Not even virtual machines but hardware machines, routers, NAS, and so on.

The only way to recover from this situation is to ifdown ifup the bridge. Then it recovers until it happens again.

When I remove the bridge no problems. But I was not able to test it since I need the bridge up.

I'm investigating macvtap instead of bridge...
