Previous administrator elected to harden the VMX files of all VMs to prevent unwanted downtime from individuals installing VMware tools upgrades manually.
I agree with him and understand in prior versions it was a good idea to disable such but now with 5.1 with the fact we no longer have to reboot for tools upgrades to occur my life has become much more complicated and we constantly run into issues with VMs having tools mounted and no way to force unmount tools.
I am looking for a PowerCLI script to removed these advanced values from the VMX file for all VMs attached to a vCenter. I assume they are the following values:
isolation.tools.autoInstall.disable = true
isolation.tools.guestInitiatedUpgrade.disable = false
isolation.tools.connectable.disable=true
If there are any other values I should check, please let me know and I will review the VMX file.
