[Bug 997978] Re: KVM images lose connectivity with bridged network

[gadLinux]

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

https://bugs.launchpad.net/ubuntu/+source/core-network/+bug/1255516

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...
