module: vcenter_vm_tools_installer
short_description: Connects the VMware Tools CD installer as a CD-ROM for the guest
    operating system
description: Connects the VMware Tools CD installer as a CD-ROM for the guest operating
    system. On Windows guest operating systems with autorun, this should cause the
    installer to initiate the Tools installation which will need user input to complete.
    On other (non-Windows) guest operating systems this will make the Tools installation
    available, and a a user will need to do guest-specific actions. On Linux, this
    includes opening an archive and running the installer. To monitor the status of
    the Tools install, clients should check the Tools.Info.version-status and Tools.Info.run-state
    from Tools.get
