ovirt_host_info – Retrieve information about one or more oVirt/RHV hosts

Synopsis

  • Retrieve information about one or more oVirt/RHV hosts.

  • This module was called ovirt_host_facts before Ansible 2.9, returning ansible_facts. Note that the ovirt_host_info module no longer returns ansible_facts!

Aliases: ovirt_host_facts

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
all_content
boolean
added in 2.7
    Choices:
  • no ←
  • yes
If true all the attributes of the hosts should be included in the response.
auth
dictionary / 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_version
string
added in 2.8
Filter the hosts based on the cluster version.
fetch_nested
boolean
    Choices:
  • no
  • yes
If yes the module will fetch additional data from the API.
It will fetch only IDs of nested entity. It doesn't fetch multiple levels of nested attributes. Only the attributes of the current entity. User can configure to fetch other attributes of the nested entities by specifying nested_attributes.
nested_attributes
list
Specifies list of the attributes which should be fetched from the API.
This parameter apply only when fetch_nested is true.
pattern
-
Search term which is accepted by oVirt/RHV search backend.
For example to search host X from datacenter Y use following pattern: name=X and datacenter=Y

Notes

Note

  • This module returns a variable ovirt_hosts, which contains a list of hosts. You need to register the result with the register keyword to use it.

  • 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:

# Gather information about all hosts which names start with C(host) and
# belong to data center C(west):
- ovirt_host_info:
    pattern: name=host* and datacenter=west
  register: result
- debug:
    msg: "{{ result.ovirt_hosts }}"
# All hosts with cluster version 4.2:
- ovirt_host_info:
    pattern: name=host*
    cluster_version: "4.2"
  register: result
- debug:
    msg: "{{ result.ovirt_hosts }}"

Return Values

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

Key Returned Description
ovirt_hosts
list
On success.
List of dictionaries describing the hosts. Host attributes are mapped to dictionary keys, all hosts attributes can be found at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/host.
