    description: Mapping of service_name -> network name. Typically set

  LVMFilterEnabled:
    default: false
    description: Enables configuration of LVM2 with a filter so that devices not
                 in use on the host or explicitly allowed are ignored by
                 LVM2. Can be configured per-role.
                 When disabled, the proposed lvm.conf file will be created
                 regardless and left in /tmp/tripleo_lvmfilter.conf for
                 debugging purposes.

                 and can be configured per-role. Any block device in use at boot
                 time will be automatically allowed.
