Comment 83 for bug 997978

I am also seeing the problem on our Ganeti managed KVM under Ubuntu 12.04. In our case on those servers with higher network load, connectivity to the guest is lost but may take one to two days. The one server with low network traffic has never lost connectivity.

By the way the loss of connectivity problem does not happen with 12.04 guests running on 11.10 containers.

I have patched to the current levels but still see the problem. The kvm package installed is;
kvm 1:84+dfsg-0ubuntu16+1.0+noroms+0ubuntu14.1

Is there something else I should be looking for?

Thanks
