VMware vCenter Server 8.0.2 is broken as hell... not just MAC addresses, but also user without admin permissions is not able to edit settings and connect ISO, or it's not possible to do storage vmotion or import OVA... vCenter from version 7 is **bleep** product, not usable, always broken, unsecure, etc... that's how it looks when VMware started saving money and delegated all work to India...
