Unmanagedstatus 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.
For more information, see the Unmanaged VMware Tools section in the VMware Tools Installation Guide For Operating System Specific Packages.
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).
so, it's not really a problem.
