Has anyone successfully created a virtual appliance or Vapp using the VMWare Studio profile
Indeed. Unless you know exactly, precisely what libraries, external commands and utilities your application needs, we do not recommend using the JeOS templates. It is an experimental feature, as you'll read in the manual, and may not work the way you intended. Use the standard templates (*not* JeOS templates, nor Application Director templates) for CentOS; you will have much more success.
