The UNITY feature was introduced in recent hosted platforms.
To be able to use it the VM must have the vmware-tools installed and on the host the authorisation service must be running.
To disable this feature for all VMs set this line in config.ini
isolation.tools.unity.disable = “true”
If you do not want to disable Unity globally you can reduce the amount of files created in the cache -subdirectory by adding this lines to the vmx-file
unity.enableLaunchMenu = “FALSE”
unity.showBadges = “FALSE”
unity.showBorders = “FALSE”
unity.wasCapable = “FALSE”
