ESXi 6.0 & 6.5 VMware Tools Missing or Not Started

Ran into this one after upgrading my lab to ESXi 6.5, the VMware tools status was showing "Installed but not running" on the VMs:
Then after rebooting them (with "check and upgrade VMware tools before each power on" enabled) the VMware tools status went to "Not installed" on some of the VMs.

It turns out that CUCM, CUC, CIM&P & UCCX are all affected when v10.x of the VMware tools are in use, SELinux interferes with it & the resulting logs can also fill up the free disk space. Full bug details: CSCux90747
There's separate patches for CUCM, CUC, CIM&P & UCCX to resolve this, at the time of writing:

  • CUCM & CUC - ciscocm.VMwareTools2016c.cop.sgn
  • CIM&P - ciscocm.IMP_VMwareTools2016c.cop.sgn
  • UCCX - ciscouccx.VMwareTools2016V2.cop.sgn
At least for UCCX after the patch I still had to reinstall the VMware tools manually via utils vmtools refresh from the CLI after mounting the install ISO.


  1. These means that your are successfully running all those servers on ESXi 6.5? The compatibility matrix for CUCM does not list 6.5 so I'm trying to find out if it is possible.

  2. Yes they all work OK in ESXi 6.5, however I've only tested in my lab, not on a production deployment.
