vmtools has a simple upgrade in Cisco’s CUCM and IM & Presence.

  1. Start the vmtools guest install in interactive mode.
  2. utils os secure permissive
  3. utils vmtools refresh
  4. (automatic reboot)
  5. utils os secure enforce

However, if you forget the utils os secure permissive command you will receive the following error during bootup and vmtools will not be upgraded: init: vmware-tools post-stop process terminated with status 1
