VMware Transparent Page Sharing change


So..Transparent Page Sharing (TPS) is turned off after the most current ESXi 5.5 update 2. And a KB article is available for it but why? Why?

It is quite easy to bring it back the way it used to be but will need an extra reboot.

After patching, using your trusty vMA, issue the following command on each host.

esxcfg-advcfg --vihost HOSTNAME -set 0 Mem.ShareForceSalting

esxcfg-advcfg --vihost HOSTNAME -get Mem.ShareForceSalting

Value of Share force salting is 0
