aa-profile-mode | string

Default: disable

Experimental enable apparmor profile. Valid settings: 'complain', 'enforce' or 'disable'. AA disabled by default.

action-managed-upgrade | boolean

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.

authorized-keys-path | string

Default: {homedir}/.ssh/authorized_keys

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 .

bridge-interface | string

Default: br100

Bridge interface to be configured

bridge-ip | string

Default: 11.0.0.1

IP to be assigned to bridge interface

bridge-netmask | string

Default: 255.255.255.0

Netmask to be assigned to bridge interface

ceph-osd-replication-count | int

Default: 3

This value dictates the number of replicas ceph must make of any object it stores withing 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).

ceph-pool-weight | int

Default: 30

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.

config-flags | string

Comma-separated list of key=value config flags. These values will be placed in the nova.conf [DEFAULT] section.

cpu-mode | string

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.

cpu-model | string

Set to a named libvirt CPU model (see names listed in /usr/share/libvirt/cpu_map.xml). Only has effect if cpu_mode='custom' and virt_type='kvm|qemu'.

enable-resize | boolean

Enable instance resizing, which requires that passwordless SSH access be setup between compute hosts.

Default: eth1

Network interface on which to build bridge

harden | string

Apply system hardening. Supports a space-delimited list of modules to run. Supported modules currently include os, ssh, apache and mysql.

hugepages | string

The pecentage 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.

instances-path | string

Path used for storing Nova instances data - empty means default of /var/lib/nova/instances.

libvirt-image-backend | string

Tell Nova which libvirt image backend to use. Supported backends are rbd, lvm and qcow2. If no backend is specified, the Nova default (qcow2) is used. Note that rbd imagebackend is only supported with >= Juno.

manage-neutron-plugin-legacy-mode | boolean

Default: True

If True nova-compute will install neutron packages for the plugin stipulated by nova-cloud-controller. The option is only available for backward compatibility for deployments which do not use the neutron-api charm. Please do not enable this on new deployments.

migration-auth-type | string

TCP authentication scheme for libvirt live migration. Available options include ssh.

multi-host | string

Default: yes

Whether to run nova-api and nova-network on the compute nodes.

nagios_context | string

Default: juju

Used by the nrpe-external-master subordinate charm. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: . juju-myservice-0 . If you're running multiple environments with the same services in them this allows you to differentiate between them.

nagios_servicegroups | string

A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup.

nova-config | string

Default: /etc/nova/nova.conf

Full path to Nova configuration file.

openstack-origin | string

Default: distro

Repository from which to install. May be one of the following: distro (default), ppa:somecustom/ppa, a deb url sources entry or a supported Ubuntu Cloud Archive (UCA) release pocket. . Supported UCA sources include: . cloud:<series>-<openstack-release> cloud:<series>-<openstack-release>/updates cloud:<series>-<openstack-release>/staging cloud:<series>-<openstack-release>/proposed . For series=Precise we support UCA for openstack-release= * icehouse . For series=Trusty we support UCA for openstack-release= * juno * kilo * ... . NOTE: updating this setting to a source that is known to provide a later version of OpenStack will trigger a software upgrade. .

openstack-origin-git | string

Specifies a default OpenStack release name, or a YAML dictionary listing the git repositories to install from. The default Openstack release name may be one of the following, where the corresponding OpenStack github branch will be used: * liberty * mitaka * master The YAML must minimally include requirements, neutron, and nova repositories, and may also include repositories for other dependencies: repositories: - {name: requirements, repository: 'git://github.com/openstack/requirements', branch: master} - {name: neutron, repository: 'git://github.com/openstack/neutron', branch: master} - {name: nova, repository: 'git://github.com/openstack/nova', branch: master release: master

pci-passthrough-whitelist | string

Sets the pci_passthrough_whitelist option in nova.conf with is used to allow pci passthrough to the VM of specific devices, for example for SR-IOV.

prefer-ipv6 | boolean

If True enables IPv6 support. The charm will expect network interfaces to be configured with an IPv6 address. If set to False (default) IPv4 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.

rabbit-user | string

Default: nova

Username used to access rabbitmq queue.

rabbit-vhost | string

Default: openstack

Rabbitmq vhost.

rbd-client-cache | string

Enable/disable rbd client cache. Leaving this value unset will result in default Ceph rbd client settings being used (rbd cache is enabled by default for Ceph >= Giant). Supported values here are "enabled" or "disabled".

rbd-pool | string

Default: nova

RBD pool to use with Nova libvirt RBDImageBackend. Only required when you have libvirt-image-backend set to 'rbd'.

Setting this to True will allow supporting services to log to syslog.
