Doesn't everybody? :-) It hard codes the mac addresses in the config files when I setup the domU. Your reply did get me to look at the config file though and I see that the date stamp on the config file is from Dec. It looks like something else changed the mac address and the upgrade just made an ifcfg-eth0 file to match. Since this machine is a sandbox it does not run very much. It is possible I missed a previous change. FWIW, I just upgraded another domU and it went flawlessly. Sorry for the noise and thanks for the info.
