New in version 2.3.

Synopsis

  • This module manage affinity labels in oVirt/RHV. It can also manage assignments of those labels to hosts and VMs.

Aliases: ovirt_affinity_labels

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.7
  • ovirt-engine-sdk-python >= 4.2.4

Parameters

Parameter Choices/Defaults Comments
auth
- / required
Dictionary with values needed to create HTTP/HTTPS connection to oVirt:
username[required] - The name of the user, something like admin@internal. Default value is set by OVIRT_USERNAME environment variable.
password[required] - The password of the user. Default value is set by OVIRT_PASSWORD environment variable.
url - A string containing the API URL of the server, usually something like `https://server.example.com/ovirt-engine/api`. Default value is set by OVIRT_URL environment variable. Either url or hostname is required.
hostname - A string containing the hostname of the server, usually something like `server.example.com`. Default value is set by OVIRT_HOSTNAME environment variable. Either url or hostname is required.
token - Token to be used instead of login with username/password. Default value is set by OVIRT_TOKEN environment variable.
insecure - A boolean flag that indicates if the server TLS certificate and host name should be checked.
ca_file - A PEM file containing the trusted CA certificates. The certificate presented by the server will be verified using these CA certificates. If `ca_file` parameter is not set, system wide CA certificate store is used. Default value is set by OVIRT_CAFILE environment variable.
kerberos - A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication.
headers - Dictionary of HTTP headers to be added to each API call.
cluster
-
Name of the cluster where vms and hosts resides.
fetch_nested
boolean
added in 2.3
    Choices:
  • no
  • yes
If True the module will fetch additional data from the API.
It will fetch IDs of the VMs disks, snapshots, etc. User can configure to fetch other attributes of the nested entities by specifying nested_attributes.
hosts
-
List of the hosts names, which should have assigned this affinity label.
name
- / required
Name of the affinity label to manage.
nested_attributes
-
added in 2.3
Specifies list of the attributes which should be fetched from the API.
This parameter apply only when fetch_nested is true.
poll_interval
-
Default:
3
Number of the seconds the module waits until another poll request on entity status is sent.
state
-
    Choices:
  • present ←
  • absent
Should the affinity label be present or absent.
timeout
-
Default:
180
The amount of time in seconds the module should wait for the instance to get into desired state.
vms
-
List of the VMs names, which should have assigned this affinity label.
wait
boolean
    Choices:
  • no
  • yes ←
True if the module should wait for the entity to get into desired state.

Notes

Note

  • In order to use this module you have to install oVirt Python SDK. To ensure it’s installed with correct version you can create the following task: pip: name=ovirt-engine-sdk-python version=4.2.4

Examples

# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

# Create(if not exists) and assign affinity label to vms vm1 and vm2 and host host1
- ovirt_affinity_label:
    name: mylabel
    cluster: mycluster
    vms:
      - vm1
      - vm2
    hosts:
      - host1

# To detach all VMs from label
- ovirt_affinity_label:
    name: mylabel
    cluster: mycluster
    vms: []

# Remove affinity label
- ovirt_affinity_label:
    state: absent
    name: mylabel

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key Returned Description
affinity_label
dictionary
 On success if affinity label is found.
Dictionary of all the affinity label attributes. Affinity label attributes can be found on your oVirt/RHV instance at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/affinity_label.
id
string
 On success if affinity label is found.
