description: >
  Libvirt service configured with Puppet

parameters:
  ServiceData:
    default: {}
    description: Dictionary packing service data
    type: json
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry.  This
                 mapping overrides those in ServiceNetMapDefaults.
    type: json
  DefaultPasswords:
    default: {}
    type: json
  RoleName:
    default: ''
    description: Role name on which the service is applied
    type: string
  RoleParameters:
    default: {}
    description: Parameters specific to the role
    type: json
  EndpointMap:
    default: {}
    description: Mapping of service endpoint -> protocol. Typically set
                 via parameter_defaults in the resource registry.
    type: json
  CephClientUserName:
    default: openstack
    type: string
  CephClientKey:
    description: The Ceph client key. Can be created with ceph-authtool --gen-print-key.
    type: string
    hidden: true
  CephClusterFSID:
    type: string
    description: The Ceph cluster FSID. Must be a UUID.
  CinderEnableRbdBackend:
    default: false
    description: Whether to enable or not the Rbd backend for Cinder
    type: boolean
  NovaComputeLibvirtType:
    type: string
    default: kvm
  LibvirtEnabledPerfEvents:
    type: comma_delimited_list
    default: []
    description: This is a performance event list which could be used as monitor.
                 For example - ``enabled_perf_events = cmt, mbml, mbmt``
                 The supported events list can be found in
                 https://libvirt.org/html/libvirt-libvirt-domain.html ,
                 which you may need to search key words ``VIR_PERF_PARAM_*``
  MonitoringSubscriptionNovaLibvirt:
    default: 'overcloud-nova-libvirt'
    type: string
  EnableInternalTLS:
    type: boolean
    default: false
  UseTLSTransportForLiveMigration:
    type: boolean
    default: true
    description: If set to true and if EnableInternalTLS is enabled, it will
                 set the libvirt URI's transport to tls and configure the
                 relevant keys for libvirt.
  InternalTLSCAFile:
    default: '/etc/ipa/ca.crt'
    type: string
    description: Specifies the default CA cert to use if TLS is used for
                 services in the internal network.
  LibvirtCACert:
    type: string
    default: ''
    description: This specifies the CA certificate to use for TLS in libvirt.
                 This file will be symlinked to the default CA path in libvirt,
                 which is /etc/pki/CA/cacert.pem. Note that due to limitations
                 GNU TLS, which is the TLS backend for libvirt, the file must
                 be less than 65K (so we can't use the system's CA bundle).
                 This parameter should be used if the default (which comes from
                 the InternalTLSCAFile parameter) is not desired. The current
                 default reflects TripleO's default CA, which is FreeIPA.
                 It will only be used if internal TLS is enabled.
  MigrationSshKey:
    type: json
    description: >
      SSH key for migration.
      Expects a dictionary with keys 'public_key' and 'private_key'.
      Values should be identical to SSH public/private key files.
    default:
      public_key: ''
      private_key: ''
  MigrationSshPort:
    default: 2022
    description: Target port for migration over ssh
    type: number
