Default value is set by OVIRT_USERNAME environment variable.
cluster
-
Name of the cluster, where VM pool should be created.
comment
-
Comment of the Virtual Machine pool.
description
-
Description of the VM pool.
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.
id
-
added in 2.8
ID of the vmpool to manage.
name
- / required
Name of the VM pool to manage.
nested_attributes
list
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
integer
Default:
3
Number of the seconds the module waits until another poll request on entity status is sent.
prestarted
-
Number of pre-started VMs defines the number of VMs in run state, that are waiting to be attached to Users.
Default value is set by engine.
state
-
    Choices:
  • present ←
  • absent
Should the VM pool be present/absent.
Note that when state is absent all VMs in VM pool are stopped and removed.
template
-
Name of the template, which will be used to create VM pool.
timeout
integer
Default:
180
The amount of time in seconds the module should wait for the instance to get into desired state.
type
-
    Choices:
  • manual
  • automatic
Type of the VM pool. Either manual or automatic.
manual - The administrator is responsible for explicitly returning the virtual machine to the pool. The virtual machine reverts to the original base image after the administrator returns it to the pool.
Automatic - When the virtual machine is shut down, it automatically reverts to its base image and is returned to the virtual machine pool.
Default value is set by engine.
vm_count
-
Number of VMs in the pool.
Default value is set by engine.
vm_per_user
-
Maximum number of VMs a single user can attach to from this pool.
Default value is set by engine.
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:

# Create VM pool from template
- ovirt_vmpool:
    cluster: mycluster
    name: myvmpool
    template: rhel7
    vm_count: 2
    prestarted: 2
    vm_per_user: 1

# Remove vmpool, note that all VMs in pool will be stopped and removed:
- ovirt_vmpool:
    state: absent
    name: myvmpool

# Change Pool Name
- ovirt_vmpool:
    id: 00000000-0000-0000-0000-000000000000
    name: "new_pool_name"

Return Values

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

Key Returned Description
id
string
 On success if VM pool is found.
ID of the VM pool which is managed

Sample:
7de90f31-222c-436c-a1ca-7e655bd5b60c
vm_pool
dictionary
 On success if VM pool is found.
Dictionary of all the VM pool attributes. VM pool attributes can be found on your oVirt/RHV instance at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/vm_pool.
