[Bug 633392] Re: Bridged Guests losing network connectivity

[Andrew Klettke]

Soren:

See this bug for more info from me on this:
https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/584048

a) I'll need to find time to set up this test, I'm working with you guys on this while I also have internal issues here at work, so bear with me.
b) No, when I SSH to the VM from my firewall and the connection is reset, the VM is inaccessible and the ARP entry on my firewall changes to the MAC address of the physical interface on the host. I can't ping out from the VM, either; all network connectivity is lost. If I'm NOT running a VM and just bridging as Serge's example above had me do, I can immediately SSH back into the box no problem, but the connection interruption still occurs.
c) The output of these commands looks exactly the same before, after, and during the problem.
