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

[Metin Akat]

This bug also affects me.
I run several VMs on the same host. A mix of ubuntu 11.10 and 12.04.  The problem occurs regardless of guest OS.
I was experiencing the problem for months, though it was occuring rarely and I didn't search for a solution.  Recently it started happening every day (sometimes twice a day), because we started using the machines in question more heavily.

I can easily confirm that this happens on high network traffic machines.
It never occurs on ones with lower traffic, and it always occurs after a
machine's network traffic increases for some reason (services on it
start being used more frequently etc.)

Now I'll install Serge's PPA and we'll see what happens. Please, correct
me if I'm wrong, but as far as I understood, I only need to install that
on the host, right?
