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
integer
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
string
    Choices:

Should the VM pool be present/absent.
Note that when state is absent all VMs in VM pool are stopped and removed.

string
    Choices:

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.

Amount of memory of the Virtual Machine. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB).
Default value is set by engine.
memory_guaranteed
string
Amount of minimal guaranteed memory of the Virtual Machine. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB).
memory_guaranteed parameter can't be lower than memory parameter.
Default value is set by engine.
memory_max
string
Upper bound of virtual machine memory up to which memory hot-plug can be performed. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB).

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=4.4.0

Examples

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

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

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

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

- name: Create vm pool and override the pool values
  ovirt.ovirt.ovirt_vmpool:
    cluster: mycluster
    name: vmpool
    template: blank
    vm_count: 2
    prestarted: 1
    vm_per_user: 1
    vm:
      memory: 4GiB
      memory_guaranteed: 4GiB
      memory_max: 10GiB
