I am having the same issues...IP's GW, are all the same as previous config, but it fails when testing the managment network.
Tried switching the vnics. still no luck...completely clueless.
It should have been a simple upgrade. Only one host..luckily I had no VMS...but I would like to get this host back on line..
think I'm gonna revert back 4.1 and reinstall just to back track.
