vSphere 5 vCenter Appliance first take

UTC. Do not change the timezone on the appliance or the embedded DB2 database will not start. 

Also watch for the DB2 logsize: http://kb.vmware.com/kb/1005259

Bugs to work out? Nahhhhh..

Other than those...few..gaping holes, I think VMware's got something going for it.
