Parameters

Parameter	Comments
api_password string	Password of the user to login into OpenNebula RPC server. If not set then the value of the ONE_PASSWORD environment variable is used. if both api_username or api_password are not set, then it will try authenticate with ONE auth file. Default path is “~/.one/one_auth”. Set environment variable ONE_AUTH to override this path.
api_url string	URL of the OpenNebula RPC server. It is recommended to use HTTPS so that the username/password are not transferred over the network unencrypted. If not set then the value of the ONE_URL environment variable is used.
api_username string	Name of the user to login into the OpenNebula RPC server. If not set then the value of the ONE_USERNAME environment variable is used.
attributes dictionary	A dictionary of key/value attributes to add to new instances, or for setting state of instances with these attributes. Keys are case insensitive and OpenNebula automatically converts them to upper case. Be aware NAME is a special attribute which sets the name of the VM when it’s deployed. # character(s) can be appended to the NAME and the module will automatically add indexes to the names of VMs. For example’:’ NAME':' foo-### would create VMs with names foo-000, foo-001,… When used with count_attributes and exact_count the module will match the base name without the index part. Default: {}
count integer	Number of instances to launch Default: 1
count_attributes dictionary	A dictionary of key/value attributes that can only be used with exact_count to determine how many nodes based on a specific attributes criteria should be deployed. This can be expressed in multiple ways and is shown in the EXAMPLES section.
count_labels list / elements=string	A list of labels that can only be used with exact_count to determine how many nodes based on a specific labels criteria should be deployed. This can be expressed in multiple ways and is shown in the EXAMPLES section.
cpu float	Percentage of CPU divided by 100 required for the new instance. Half a processor is written 0.5.
datastore_id integer added in community.general 0.2.0	Name of Datastore to use to create a new instance
datastore_name string added in community.general 0.2.0	Name of Datastore to use to create a new instance
disk_saveas dictionary	Creates an image from a VM disk. It is a dictionary where you have to specify name of the new image. Optionally you can specify disk_id of the disk you want to save. By default disk_id is 0. NOTE: This operation will only be performed on the first VM (if more than one VM ID is passed) and the VM has to be in the poweredoff state. Also this operation will fail if an image with specified name already exists.
disk_size list / elements=string	The size of the disk created for new instances (in MB, GB, TB,…). NOTE: If The Template hats Multiple Disks the Order of the Sizes is matched against the order specified in template_id/template_name.
exact_count integer	Indicates how many instances that match count_attributes and count_labels parameters should be deployed. Instances are either created or terminated based on this value. NOTE: Instances with the least IDs will be terminated first.
group_id integer	ID of the group which will be set as the group of the instance
hard boolean	Reboot, power-off or terminate instances hard. Choices: false ← (default) true
instance_ids aliases: ids list / elements=integer	A list of instance ids used for states: absent, running, rebooted, poweredoff.
labels list / elements=string	A list of labels to associate with new instances, or for setting state of instances with these labels. Default: []
memory string	The size of the memory for new instances (in MB, GB, …)
mode string	Set permission mode of the instance in octet format, for example 0600 to give owner use and manage and nothing to group and others.
networks list / elements=dictionary	A list of dictionaries with network parameters. See examples for more details. Default: []
owner_id integer	ID of the user which will be set as the owner of the instance
persistent boolean added in community.general 0.2.0	Create a private persistent copy of the template plus any image defined in DISK, and instantiate that copy. Choices: false ← (default) true
state string	present - create instances from a template specified with template_id/template_name. running - run instances poweredoff - power-off instances rebooted - reboot instances absent - terminate instances Choices: "present" ← (default) "absent" "running" "rebooted" "poweredoff"
template_id integer	ID of a VM template to use to create a new instance
template_name string	Name of VM template to use to create a new instance
updateconf dictionary added in community.general 6.3.0	When instance_ids is provided, updates running VMs with the updateconf API call. When new VMs are being created, emulates the updateconf API call via direct template merge. Allows for complete modifications of the CONTEXT attribute.
vcpu integer	Number of CPUs (cores) new VM will have.
vm_start_on_hold boolean	Set to true to put vm on hold while creating Choices: false ← (default) true
wait boolean	Wait for the instance to reach its desired state before returning. Keep in mind if you are waiting for instance to be in running state it doesn’t mean that you will be able to SSH on that machine only that boot process have started on that instance, see ‘wait_for’ example for details. Choices: false true ← (default)
wait_timeout integer	How long before wait gives up, in seconds Default: 300

Attributes

Attribute	Support	Description
check_mode	Support: full	Can run in check_mode and return changed status prediction without modifying target.
diff_mode	Support: none	Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.
