How do I be sure that LMS will not force me to license every CPU in the VMWARE cluster whether are not they are assigned to a VM?

The VM that the Oracle DB is running on can only see the CPU's that VMWare has given to that VM. The VM wont even see the total number of CPUs on the host.

Mark, I know that VMWARE can do that, but will LMS accept that has HARD PARTITIONING?  That is what worries me.  We switched to OVM for Oracle to avoid licensing cost of VMWARE (per Oracle), but have found that OVM is a POS!

Oracle licensing is tied to host server processors.  If you need the ability to use vMotion and you have 10 dual processor hosts then you need to license all 20 CPUs, however, if you want vMotion but will always vMotion between two distinct physical hosts then you need to only license 2 server (or 4 CPUs).  You can license only 1 server as long as pin the VM to always run on one physical host as well as configure it to never vMotion to a different host.  Just like a physical server environment, as long as the physical server is down, your Oracle is also down.  Refer to link below for more information:
