      'enforce' or 'disable'.
      .
      AA disabled by default.
    type: string
    value: disable
  action-managed-upgrade:
    default: true
    description: |
      If True enables openstack upgrades for this charm via juju actions.
      You will still need to set openstack-origin to the new repository but
      instead of an upgrade running automatically across all units, it will
      wait for you to execute the openstack-upgrade action for this charm on
      each unit. If False it will revert to existing behavior of upgrading
      all units on config change.
    type: boolean
    value: false
  authorized-keys-path:
    default: true
    description: |
      Only used when migration-auth-type is set to ssh.
      .
      Full path to authorized_keys file, can be useful for systems with
      non-default AuthorizedKeysFile location. It will be formatted using the
      following variables:
      .
        homedir - user's home directory
        username - username
      .
    type: string
    value: '{homedir}/.ssh/authorized_keys'
  bridge-interface:
    default: true
    description: Bridge interface to be configured.
    type: string
    value: br100
  bridge-ip:
    default: true
    description: IP to be assigned to bridge interface.
    type: string
    value: 11.0.0.1
  bridge-netmask:
    default: true
    description: Netmask to be assigned to bridge interface.
    type: string
    value: 255.255.255.0
  ceph-osd-replication-count:
    default: true
    description: |
      This value dictates the number of replicas ceph must make of any
      object it stores within the nova rbd pool. Of course, this only
      applies if using Ceph as a backend store. Note that once the nova
      rbd pool has been created, changing this value will not have any
      effect (although it can be changed in ceph by manually configuring
      your ceph cluster).
    type: int
    value: 3
  ceph-pool-weight:
    default: true
    description: |
      Defines a relative weighting of the pool as a percentage of the total
      amount of data in the Ceph cluster. This effectively weights the number
      of placement groups for the pool created to be appropriately portioned
      to the amount of data expected. For example, if the ephemeral volumes
      for the OpenStack compute instances are expected to take up 20% of the
      overall configuration then this value would be specified as 20. Note -
      it is important to choose an appropriate value for the pool weight as
      this directly affects the number of placement groups which will be
      created for the pool. The number of placement groups for a pool can
      only be increased, never decreased - so it is important to identify the
      percent of data that will likely reside in the pool.
    type: int
    value: 30
  config-flags:
    default: true
    description: |
      Comma-separated list of key=value config flags. These values will be
      placed in the nova.conf [DEFAULT] section.

    default: true
    description: |
      Set to 'host-model' to clone the host CPU feature flags; to
      'host-passthrough' to use the host CPU model exactly; to 'custom' to
      use a named CPU model; to 'none' to not set any CPU model. If
      virt_type='kvm|qemu', it will default to 'host-model', otherwise it will
      default to 'none'. Defaults to 'host-passthrough' for ppc64el, ppc64le
      if no value is set.
    type: string
  cpu-model:
    default: true
    description: |

    default: true
    description: |
      Default compute node availability zone.
      .
      This option determines the availability zone to be used when it is not
      specified in the VM creation request. If this option is not set, the
      default availability zone 'nova' is used.
      .
      NOTE: Availability zones must be created manually using the
      'openstack aggregate create' command.
      .
    type: string
    value: nova
  disk-cachemodes:

      Configure libvirt or lxd for live migration.
      .
      Live migration support for lxd is still considered experimental.
      .
      NOTE: This also enables passwordless SSH access for user 'root' between
      compute hosts.
    type: boolean
    value: false
  enable-resize:
    default: true
    description: |

      to run. Supported modules currently include os, ssh, apache and mysql.
    type: string
  hugepages:
    default: true
    description: |
      The percentage of system memory to use for hugepages eg '10%' or the
      total number of 2M hugepages - eg "1024".
      For a systemd system (wily and later) the prefered approach is to enable
      hugepages via kernel parameters set in MAAS and systemd will mount them
      automatically.
      .
      NOTE: For hugepages to work it must be enabled on the machine deployed
      to. This can be accomplished by setting kernel parameters on capable
      machines in MAAS, tagging them and using these tags as constraints in the
      model.

      instance the hostname would be something like:
      .
        juju-myservice-0

      NOTE: updating this setting to a source that is known to provide
      a later version of OpenStack will trigger a software upgrade.
      .

        repositories:
        - {name: requirements,
           repository: 'git://github.com/openstack/requirements',
           branch: master}
        - {name: neutron,

      Example applications: GPU processing, SR-IOV networking, etc.
      .
      NOTE: For PCI passthrough to work IOMMU must be enabled on the machine
      deployed to. This can be accomplished by setting kernel parameters on
      capable machines in MAAS, tagging them and using these tags as
      constraints in the model.
    type: string
  prefer-ipv6:
    default: true
    description: |
      If True enables IPv6 support. The charm will expect network interfaces

      is expected.
      .
      NOTE: these charms do not currently support IPv6 privacy extension. In
      order for this charm to function correctly, the privacy extension must be
      disabled and a non-temporary address must be configured/available on
      your network interface.
