I have the same symptoms with Ubuntu 12. The network is not reachable 3-4 times a day, for about 1-2 minutes but recovers by itself. Does not seem traffic/load related as it also happens, when there is nothing on. - No dhcp - bridged network with static ip's for guests - atm only running one VM Ubuntu 12 - pretty bare host install with just kvm and libvirt - no relevant output in any log files
