Knife oVirt

• fog
• rbovirt
• chef
• knife-cloud

Once you have ChefDK installed you can run:

chef gem install knife-ovirt

You can set the authorization parameters for ovirt in your knife.rb file like this:

knife[:ovirt_username]="Your oVirt Username"
knife[:ovirt_url]="Your oVirt API URL"
knife[:ovirt_password]="Your OVirt Password"

You can also specify these options on the command line as (--ovirt-username, --ovirt-password, --ovirt-url)

These parameters are required for all the commands below, and can be specified in a knife.rb config file or on the command line.

The plugin provides

List the Virtual Machines that are defined on the oVirt System.

Create a new server in the oVirt cluster based off an existing template. One of --ovirt-template-name or --ovirt-template is required.

• --ovirt-cores <#> specify the number of cores >=1 for the new VM

• --ovirt-memory <name> specify the amount of memory for the new VM in bytes

• --ovirt-template <id> specify a template ID to clone the new VM from

• --ovirt-template-name <name> specify the name of a template to clone the new VM from

• --ovirt-volumes <list of hashes> specify the volumes to create or attach to the new VM. for example to create a new volume and attach an existing one:

knife[:ovirt_volumes] = [
  {
    size_gb: 2,
    domain_id: 'f7a25cf2-b2d4-43d3-8180-78f8f1c48b7d',
    interface: 'virtio_scsi',
    alias: 'testvol',
    bootable: 'false'
  },
  {
    id: 'd9e995f0-1c2d-4e9f-9cdf-4eb39b619d57',
    interface: 'virtio_scsi',
  }
]

• --ovirt_cloud_init <cloud_init yaml> specify a yaml string containing the cloud_init data needed to pass to the system. One method is to do it this way in a the knife.rb config:

knife[:ovirt_cloud_init] = {
  ssh_authorized_keys: [File.read("#{ENV['HOME']}/.ssh/ovirt.pub")],
  user: knife[:ssh_user],
  ip: knife[:bootstrap_ip_address],
  netmask: '255.255.255.0',
  gateway: '192.168.1.1',
  nicname: 'eth0',
  dns: '192.168.1.1',
  domain: 'example.com',
  hostname: knife[:chef_node_name],
}.to_yaml

Delete a Virtual Machine or list of Virtual Machines

List the storage domains that are currently defined on the oVirt System

List the volumes that are currently defined on the oVirt System

Create a new volume on the oVirt System

• --vm-id <id> Virtual Machine to attach the volume to

• --volume-alias <alias> alias for the volume

• --volume-bootable <boolean> should this volume be bootable

• --volume-domain-id <id> template to build server from

• --volume-interface <interface> interface type for volume

• --volume-size <size> Size of volume in Gigabytes
