We're looking very solid on kernel 3.8.0-30, under heavy load. I count this as resolved.

This has occurred on 4 separate host machines. This tends to happen sooner / more often, to guests which generate more traffic than others. The only way to recover networking is to shutdown or force-stop the guest, and restart it. We have attempted to do a live-migration of a guest in this condition, which resulted in the source-host server kernel panicing. All host diagnostics including: ifconfig, "virsh domiflist", and "brctl show" outputs look identical to working guests. On the guest, the interface appears up, there are no syslog errors, the guest can ping it's own address, but any outgoing communication fails. This looks just like Ubuntu Precise bug #997978, which affected us last year as well..
