Once even sometimes three times per day, one of our guests loses network connections. Our ping responds with "Host unreachable", even from the dom host. I am running an Essex environment in VLAN mode. For some reason, my instance cannot renew its IP address/lease and the dhclient fails. This issue is definitely not traffic or load related because nothing is running. We have a dedicated nova network GW, KVM and we are running on OS Ubuntu 12.04.

This sounds like the bug we experienced in our environment. KVM images lose connectivity with bridged network. Try the below solution.
