For licensing on VMs, Oracle insists on licensing for underlying physical machine. So I am afraid you might have to for all physical CPUs even with VM.

Are you already using it for production environment? If yes, have you encountered any issues (performance,maintenance,support,etc.)? To make the long story short, we have this situation on a client.. they have planned to acquire a 4 CPU (physical) Intel quad core server, so on the Oracle Licensing that's 8 Processor License (EE).. time passed and the hardware vendor no longer ships that kind of machine.. and what was shipped was the 4 CPU (physical) Intel hexacore .. So with this kind of machine, they need to have 12 Processor License (EE).. hmm... well the client could opt to - buy the remaining 4 Processor License but the cost would boost up.. - or they could opt to hardware partition the server using Oracle VM by physically segmenting the server's CPU thus only the allocated CPU will only be licensed Well I got an interesting situation here, wondering if anyone on the list have also encountered this.. comments, reactions, are welcome.. -- Karl Arao <http://karlarao.wordpress.com> karlarao.wordpress.com <http://karlarao.tiddlyspot.com> karlarao.tiddlyspot.com
