opennebula_ng cookbook

Official repository for the opennebula_ng cookbook, a cookbook for managing OpenNebula via the Chef configuration management tool.

Supported Platforms

  • Debian
  • Ubuntu


To setup a minimal configuration, standalone OpenNebula server, set the following attributes to configure your network

node['opennebula_ng']['interfaces']['br0']['inet']['type'] = 'inet'
node['opennebula_ng']['interfaces']['br0']['inet']['address'] = ''
node['opennebula_ng']['interfaces']['br0']['inet']['network'] = ''
node['opennebula_ng']['interfaces']['br0']['inet']['netmask'] = ''
node['opennebula_ng']['interfaces']['br0']['inet']['broadcast'] = ''
node['opennebula_ng']['interfaces']['br0']['inet']['gateway'] = ''

And run the following recipes:

  • default
  • sunstone
  • node
  • register_nodes

This will do the following things

  • Install the Sunstone frontend
  • Configure the network, add OpenNebula bridge
  • Register the current host as an OpenNebula node

You should be able to connect to your new OpenNebula installation using



The default recipe just includes the apt_repository recipe


This recipe sets up the official OpenNebula PPA for Ubuntu (stable) You may override the specified version by manually setting node['opennebula_ng']['version']


This recipe installs the official OpenNebula LVM addon, which is not part of OpenNebula core since version 5.0 If you are using LVM block devices using the lvm driver, you're going to need this.

By default it installs the addon from the official git repository, as there are no tarball releases yet. The repository, as well as the branch (defaults to master) can be overriden using the following attributes:

node['opennebula_ng']['lvm']['repository'] = ''
node['opennebula_ng']['lvm']['branch'] = 'master'


This recipe installs and configures the sunstone frontend.

  • Installs opennebula and opennebula-sunstone packages
  • Takes care of SSH and authorized_keys configuration


This recipe turns your machine into an opennebula node

  • Configures networking according to node attributes (DANGER: touches /etc/network/interfaces)
  • Configures the OpenNebula bridge interface
  • Configures qEMU
  • Configures libvirt

MAKE SURE you configure the following attributes (e.g. create one file for each node in your wrapper cookbooks attribute dir, e.g. attributes/myhost1.rb)

if == 'myhost1'
  node['opennebula_ng']['interfaces']['br0']['inet']['type'] = 'static'
  node['opennebula_ng']['interfaces']['br0']['inet']['address'] = ''
  node['opennebula_ng']['interfaces']['br0']['inet']['network'] = ''
  node['opennebula_ng']['interfaces']['br0']['inet']['netmask'] = ''
  node['opennebula_ng']['interfaces']['br0']['inet']['broadcast'] = ''
  node['opennebula_ng']['interfaces']['br0']['inet']['gateway'] = ''

  node['opennebula_ng']['interfaces']['br0']['inet']['bridge_ports'] = 'eth0'
  node['opennebula_ng']['interfaces']['br0']['inet']['bridge_fd'] = 9
  node['opennebula_ng']['interfaces']['br0']['inet']['bridge_hello'] = 2
  node['opennebula_ng']['interfaces']['br0']['inet']['bridge_maxage'] = 12
  node['opennebula_ng']['interfaces']['br0']['inet']['bridge_stp'] = 'off'

You can also configure additional interfaces, if required

node['opennebula_ng']['interfaces']['br1']['inet']['type'] = 'static'
node['opennebula_ng']['interfaces']['br1']['inet']['address'] = ''
node['opennebula_ng']['interfaces']['br1']['inet']['network'] = ''
node['opennebula_ng']['interfaces']['br1']['inet']['netmask'] = ''
node['opennebula_ng']['interfaces']['br1']['inet']['broadcast'] = ''

node['opennebula_ng']['interfaces']['br1']['inet']['bridge_ports'] = 'eth1'
node['opennebula_ng']['interfaces']['br1']['inet']['bridge_fd'] = 9
node['opennebula_ng']['interfaces']['br1']['inet']['bridge_hello'] = 2
node['opennebula_ng']['interfaces']['br1']['inet']['bridge_maxage'] = 12
node['opennebula_ng']['interfaces']['br1']['inet']['bridge_stp'] = 'off'

Since version 4.12.1, ipv6 is also supported:

node['opennebula_ng']['interfaces']['br0']['inet6']['type'] = 'static'
node['opennebula_ng']['interfaces']['br0']['inet6']['address'] = 'fcc1:cafe:bee1:dead::1'
node['opennebula_ng']['interfaces']['br0']['inet6']['network'] = 64


Configures OpenNebula to use a MariaDB backend.

Adjust the following attributes in case they are different from the defaults:

# Default mysql database settings
node['opennebula_ng']['mysql']['server']  = 'localhost'
node['opennebula_ng']['mysql']['port']    = 0
node['opennebula_ng']['mysql']['user']    = 'oneadmin'
node['opennebula_ng']['mysql']['passwd']  = 'oneadmin'
node['opennebula_ng']['mysql']['db_name'] = 'opennebula'

Make sure you set a root password (This password will also be used for the debian-sys-maint user, in case you use Debian/Ubuntu.

node['mysqld']['root_password'] = 'get_me_from_encrypted_data_bag_maybe?'

Set the wsrep ssh auth, for example, use the root user which password we just specified:

node['mysqld']['my.cnf']['mysqld']['wsrep_sst_auth'] = "root:#{node['mysqld']['root_password']}"

In case you have multiple interfaces, you might also want to specify the IP of the interface the replication should use

node['mysqld']['my.cnf']['mysqld']['wsrep_node_address'] = 'eth1'

In case you use more than one mariadb galera node, set this attribute to include all galera nodes in your cluster

node['mysqld']['my.cnf']['mysqld']['wsrep_cluster_address'] = 'gcomm://node1,node2,node3'

Its recommended to keep one Galera node on each physical cluster (as virtual machines), and then default each machine to connect to the one their hosting. This can be done like this:

# Connect to different clusters
if == 'node1'
  default['opennebula_ng']['mysql']['server']  = 'galera.node.on.host1'
elsif == 'node2'
  default['opennebula_ng']['mysql']['server']  = 'galera.node.on.host2'
  default['opennebula_ng']['mysql']['server']  = 'galera.node.on.host1'


Use this cookbook if you want to initialize a new clusters first node:

sudo chef-client --once -o 'recipe[opennebula_ng::mariadb_galera_init]'

You can also include it (if required) in a mariadb_galera_init cookbook in your wrapper cookbook

include_recipe 'opennebula_ng::mariadb_galera_init'

This cookbook just calls mysqld::mariadb_galera_init. Having it here is useful, as we set some attributes which are not available when calling the mysqld recipe directly.


This recipe configures the /etc/one/oned.conf configuration file on the servers to connect to the mariadb cluster specified in the arguments from the mariadb_server recipe.

Note: If those values are changed, the file is not automatically updated. This is due to a bug with multiline regular expressions. See recipes/mariadb_client.rb for details


This recipe registers your hosts at oned.

The configuration is set via attributes, and supports all parameters that onehost supports.

The default is to register the node chef is currently running on, using kvm

# You can add all your nodes centrally here
node['opennebula_ng']['nodes'] = {
  myhost1: { im: 'kvm', vm: 'kvm', net: 'dummy' },
  myhost2: { im: 'kvm', vm: 'kvm', net: 'dummy' },
  myhost3: { im: 'kvm', vm: 'kvm', net: 'dummy' },


This recipe registers virtual networks using onenet.

You can specify your network configuration using the following attributes. Both fixed and ranged networks are supported.

node['opennebula_ng']['virtual_networks'] = {
  frontnet_dualstack: {
    BRIDGE: 'br0',
    GATEWAY: '',
    DNS: '',
    AR: {
      TYPE: 'IP4_6',
      IP: '',
      GLOBAL_PREFIX: '2a00:abcd:1000:f000::',
      SIZE: 100,
  backnet_ipv4: {
    BRIDGE: 'br1',

    # Multiple address-ranges are also valid
    AR: [
        TYPE: 'IP4',
        IP: '',
        SIZE: 10,
        TYPE: 'IP4',
        IP: '',
        SIZE: 10,

Note: If you later add more addresses to an existing network, the settings are not automatically updated on the nodes. The recipe skips creating a network if the network already exists.


A recipe to configure LVM datastores.

  • Installs and configures lvm packages
  • Creates datastores according to attributes

You can configure the datastores using the following attributes:

node['opennebula_ng']['lvm']['datastores'] = {
  'my datastore' => {
    DS_MAD: 'lvm',
    TM_MAD: 'lvm',
    VG_NAME: 'vg-one',
    BRIDGE_LIST: node['hostname'], # Add all hostnames of hosts accessing this datastore


This recipe configures the host to be a NFS server. It can be configured using the following attributes:

# Network to export NFS directories to, defaults to all hosts
node['opennebula_ng']['nfs']['network'] = '*' # or a network like e.g. ''

# NFS fsid. Must be unique
node['opennebula_ng']['nfs']['fsid'] = 1

# Hostname/IP of the NFS server (usually the frontend machine)
node['opennebula_ng']['nfs']['server'] = 'myhost1'


Configures the host to be an NFS client, mouting /var/lib/one from the server stored in node['opennebula_ng']['nfs']['server']


Configures the auth tokens in /var/lib/one/.one. When using a shared database, but not a shared /var/lib/one/.one directory, they need to be in sync between all servers.

You can set the shared items using the following attributes:

# Set shared passwords between all opennebula hosts for serveradmin and oneadmin
node['opennebula_ng']['one_auth']['oneadmin']['password'] = 'password_from_encrypted_data_bag_maybe?'
node['opennebula_ng']['one_auth']['serveradmin']['password'] = 'another_password'

You can also set the ssh keypair (as every OpenNebula host needs to be able to connect to the others, using the "oneadmin" user).

Hint: You can generate a keypair using the ssh-keygen command.

node['opennebula_ng']['one_auth']['oneadmin']['id_rsa'] = "-----BEGIN RSA PRIVATE KEY-----\nMIIE..."
node['opennebula_ng']['one_auth']['oneadmin'][''] = 'ssh-rsa AAAA...'

NOTE: This recipe assumes that the oneuser has id 0, and serveradmin the id 1. This is the default. If you have them set to something else, make sure to adjust the id attributes!

node['opennebula_ng']['one_auth']['oneadmin']['id'] = 0
node['opennebula_ng']['one_auth']['serveradmin']['id'] = 1

You can also configure (if needed) the oneadmin's home directory as well as the one_auth file that will be used:

node['opennebula_ng']['one_auth']['oneadmin']['home'] = '/var/lib/one'
node['opennebula_ng']['one_auth']['oneadmin']['auth_file'] = '/var/lib/one/.one/one_auth'


Please be aware, that you probably want a reverse proxy like nginx incl. SSL before you deploy OpenNebula to your production servers.

You can easily do this e.g. using the certificate and nginx cookbooks.

Contingent cookbooks

There are no cookbooks that are contingent upon this one.



  • Add node['opennebula_ng']['version'] attribute to allow installing a specific version
  • Update default OpenNebula version to 5.0


  • Add posibility to configure interfaces without an ip address (for bridges). For this to work, a safeguard was removed that prevented interface configuration to be written to /etc/network/interfaces when no address was set.


  • Re-license under GPLv3


  • Update default OpenNebula version to 4.14


  • BREAKING CHANGE: Add support for ipv6. Network configuration adaption required!
# Change
node['opennebula_ng']['interfaces']['br0']['type'] = 'inet static'
node['opennebula_ng']['interfaces']['br0']['address'] = ''

# To:
node['opennebula_ng']['interfaces']['br0']['inet']['type'] = 'static'
node['opennebula_ng']['interfaces']['br0']['inet']['address'] = ''


  • Update default OpenNebula version to 4.12.0


  • Allow multiple ARs (address-ranges) in virtual network configuration


  • Use OpenNebula 4.10 repositories. To upgrade, run apt-get dist-upgrade after deploying the cookbook. Make sure you also run the database migrations using onedb upgrade.


  • Support new address range (AR) syntax in virtual_network recipe
  • Use --sha1 when changing password for serveradmin
  • Deploy alongside id_rsa
  • Do not automatically restart network configuration. This is problematic, as it cuts off virtual machines from their network bridges.


  • Fail hard when not using a valid network configration, instead of deploying an empty /etc/network/interfaces


  • Add node['opennebula_ng']['active'] attribute, which defaults to false. On non-active opennebula hosts we won't add networks/storage/users and will disable oned, scheduler and sunstone services, as OpenNebula is not capable of running as an active-active environment due to caching issues.

Compatibility changes: - Set node['opennebula_ng']['active'] = true on your currently active (master) host


  • Add one_auth recipe, to set shared passwords for "oneadmin" and "serveradmin" users, as well as deploy ssh keys

Compatibility changes: - Renamed node['opennebula_ng']['one_auth'] attribtue to node['opennebula_ng']['one_auth']['oneadmin']['auth_file'] - Renamed node['opennebula_ng']['one_home'] attribute to node['opennebula_ng']['one_auth']['oneadmin']['home']


  • Use mariadb galera by default


  • Upgrade to OpenNebula 4.8 packages


  • Initial release of opennebula_ng
