ovirt_vmpools - Module to manage VM pools in oVirt

New in version 2.3.

Synopsis

  • Module to manage VM pools in oVirt.

Requirements (on host that executes module)

  • python >= 2.7
  • ovirt-engine-sdk-python >= 4.0.0

Options

parameter required default choices comments
auth
yes
Dictionary with values needed to create HTTP/HTTPS connection to oVirt:
username[required] - The name of the user, something like [email protected]. 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[required] - A string containing the base URL of the server, usually something like `https://server.example.com/ovirt-engine/api`. Default value is set by OVIRT_URL environment variable.
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.
cluster
no
Name of the cluster, where VM pool should be created.
description
no
Description of the VM pool.
fetch_nested
(added in 2.3)
no
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.
name
yes
Name of the the VM pool to manage.
nested_attributes
(added in 2.3)
no
Specifies list of the attributes which should be fetched from the API.
This parameter apply only when fetch_nested is true.
poll_interval
no 3
Number of the seconds the module waits until another poll request on entity status is sent.
prestarted
no
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
no present
  • 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
no
Name of the template, which will be used to create VM pool.
timeout
no 180
The amount of time in seconds the module should wait for the instance to get into desired state.
type
no
  • 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
no
Number of VMs in the pool.
Default value is set by engine.
vm_per_user
no
Maximum number of VMs a single user can attach to from this pool.
Default value is set by engine.
wait
no
True if the module should wait for the entity to get into desired state.

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_vmpools:
    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_vmpools:
    state: absent
    name: myvmpool

Return Values

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

name description returned type sample
vm_pool Dictionary of all the VM pool attributes. VM pool attributes can be found on your oVirt instance at following url: https://ovirt.example.com/ovirt-engine/api/model#types/vm_pool. On success if VM pool is found.
id ID of the VM pool which is managed On success if VM pool is found. str 7de90f31-222c-436c-a1ca-7e655bd5b60c
