This did not work for me.
I've downloaded and installed / configured the vCenter Appliance 5.5.0.10000 Build 1624811 and attempted to add 3 hosts all with fresh installs of VMware-ESXi-5.5.0-Update1-1623387-HP-5.73.21-Mar2014.iso, and all of them failed with "The Evaluation Mode license assigned to Host {ip address} has expired. Recommend updating the license."
When I log into the hosts directly with the vSphere Client, they show that they are in Evaluation Mode.
Is this a bug or a horrible feature?
