    - Name of the virtual machine to work with.
    - Virtual machine names in vCenter are not necessarily unique, which may be problematic, see C(name_match).
    - 'If multiple virtual machines with same name exists, then C(folder) is required parameter to
       identify uniqueness of the virtual machine.'
    - This parameter is required, if C(state) is set to C(poweredon), C(poweredoff), C(present), C(restarted), C(suspended)
      and virtual machine does not exists.
    - This parameter is case sensitive.
