Synopsis

This module manage affinity groups in oVirt/RHV. It can also manage assignments of those groups to VMs.

Requirements

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

python >= 2.7
ovirt-engine-sdk-python >= 4.3.0

Parameters

Parameter		Choices/Defaults	Comments
auth dictionary / required			Dictionary with values needed to create HTTP/HTTPS connection to oVirt:
	ca_file string		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.
	headers dictionary		Dictionary of HTTP headers to be added to each API call.
	hostname string		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.
	insecure boolean	Choices: no yes	A boolean flag that indicates if the server TLS certificate and host name should be checked.
	kerberos boolean	Choices: no yes	A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication.
	password string / required		The password of the user. Default value is set by `OVIRT_PASSWORD` environment variable.
	token string		Token to be used instead of login with username/password. Default value is set by `OVIRT_TOKEN` environment variable.
	url string		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.
	username string / required		The name of the user, something like admin@internal. Default value is set by `OVIRT_USERNAME` environment variable.
cluster -			Name of the cluster of the affinity group.
description -			Description of the affinity group.
fetch_nested boolean		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`.
host_enforcing boolean		Choices: no yes	If yes VM cannot start on host if it does not satisfy the `host_rule`. This parameter is support since oVirt/RHV 4.1 version.
host_rule -		Choices: negative positive	If positive all VMs in this group should run on the this host. If negative no VMs in this group should run on the this host. This parameter is support since oVirt/RHV 4.1 version.
hosts -			List of the hosts names, which should have assigned this affinity group. This parameter is support since oVirt/RHV 4.1 version.
name - / required			Name of the affinity group to manage.
nested_attributes list			Specifies list of the attributes which should be fetched from the API. This parameter apply only when `fetch_nested` is true.
poll_interval integer		Default: 3	Number of the seconds the module waits until another poll request on entity status is sent.
state -		Choices: absent present ←	Should the affinity group be present or absent.
timeout integer		Default: 180	The amount of time in seconds the module should wait for the instance to get into desired state.
vm_enforcing boolean		Choices: no yes	If yes VM cannot start if it does not satisfy the `vm_rule`.
vm_rule -		Choices: disabled negative positive	If positive all VMs in this group should run on the host defined by `host_rule`. If negative no VMs in this group should run on the host defined by `host_rule`. If disabled this affinity group doesn't take effect.
vms -			List of the VMs names, which should have assigned this affinity group.
wait boolean		Choices: no yes ←	`yes` 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=4.3.0

Examples

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

- name: Create(if not exists) and assign affinity group to VMs vm1 and vm2 and host host1
  ovirt_affinity_group:
    name: mygroup
    cluster: mycluster
    vm_enforcing: true
    vm_rule: positive
    host_enforcing: true
    host_rule: positive
    vms:
      - vm1
      - vm2
    hosts:
      - host1

- name: Detach VMs from affinity group and disable VM rule
  ovirt_affinity_group:
    name: mygroup
    cluster: mycluster
    vm_enforcing: false
    vm_rule: disabled
    host_enforcing: true
    host_rule: positive
    vms: []
    hosts:
      - host1
      - host2

- name: Remove affinity group
  ovirt_affinity_group:
    state: absent
    cluster: mycluster
    name: mygroup

Return Values

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

Key	Returned	Description
affinity_group string	On success if affinity group is found.	Dictionary of all the affinity group attributes. Affinity group attributes can be found on your oVirt/RHV instance at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/affinity_group.
id string	On success if affinity group is found.	ID of the affinity group which is managed Sample: 7de90f31-222c-436c-a1ca-7e655bd5b60c
