Interesting, but this does rather assume that Oracle LMS will recognise licence partitioning beneath the VMware cluster level - is there any documentation to support this?
Of course Oracle and DRS host affinity rules (i.e. allowed or not) got a lot of publicity last year following this interview: http://www.licenseconsulting.eu/2012/08/29/vmworld-richard-garsthagen-oracle-on-licensing-vmware-virtualized-environments/
And whether Oracle wlll extend something like Oracle Trusted Partitions (http://www.veriton.co.uk/roller/fmw/entry/oracle_trusted_partitions_dynamic_and), to apply to any hardware/hypervisor remains to be seen...
