VMWare Mem Share Force Salting

VMWare Mem Share Force Salting

What is meant by Intra-VM and Inter-VM in the context of Transparent Page Sharing?

Intra-VM means that TPS will de-duplicate identical pages of memory within a virtual machine, but will not share the pages with any other virtual machines.
Inter-VM mean that TPS will de-duplicate identical pages of memory within a virtual machine and will also share the duplicates with one of more other virtual machines with the same content.

How do I re-enable inter-VM TPS for all virtual machines after deploying an ESX Update release that no longer has inter-VM TPS enabled by default?
