  Libvirt service configured with Puppet

parameters:
  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
  EndpointMap:
    default: {}
    description: Mapping of service endpoint -> protocol. Typically set
                 via parameter_defaults in the resource registry.
    type: json
  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.
  LibvirtCACert:
    type: string
    default: '/etc/ipa/ca.crt'
    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). The
                 current default reflects TripleO's default CA, which is
                 FreeIPA. It will only be used if internal TLS is enabled.
