The Unmanaged status for VMware Tools indicates that the Operating System specific Package (OSP) Tools are being used. This means that VMware Tools is not being managed by the VI/vSphere Client to keep them up-to-date. OSP Tools enables managing VMware Tools from within the guest operating system in the same way as other standard software/application. This message will also appear when open-vm-tools package is installed. See the note at the end of this section.
Note: As of Linux kernel version 3.9 or later, VMware supports the open-vm-tools package where it is included in a Linux distribution or its official repositories. For more information, especially about supported Linux distributions, see VMware support of open-vm-tools (2073803).
