Synopsis ¶

Module to manage Virtual Machine and floating disks in oVirt/RHV.

Aliases: ovirt_disks

Requirements ¶

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

python >= 2.7
ovirt-engine-sdk-python >= 4.2.4

Parameters ¶

Parameter	Choices/Defaults	Comments
auth - / 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.
bootable -		True if the disk should be bootable. By default when disk is created it isn't bootable.
description - added in 2.5		Description of the disk image to manage.
download_image_path - added in 2.3		Path on a file system where disk should be downloaded. Note that you must have an valid oVirt/RHV engine CA in your system trust store or you must provide it in `ca_file` parameter. Note that the disk is not downloaded when the file already exists, but you can forcibly download the disk when using `force` I (true).
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`.
force - added in 2.3		Please take a look at `image_path` documentation to see the correct usage of this parameter.
format -	Choices: raw cow	Specify format of the disk. Note that this option isn't idempotent as it's not currently possible to change format of the disk via API.
id -		ID of the disk to manage. Either `id` or `name` is required.
image_provider - added in 2.4		When `state` is exported disk is exported to given Glance image provider. `IMPORTANT` There is no reliable way to achieve idempotency, so every time you specify this parameter the disk is exported, so please handle your playbook accordingly to not export the disk all the time. This option is valid only for template disks.
interface -	Choices: virtio ← ide virtio_scsi	Driver of the storage interface. It's required parameter when creating the new disk.
logical_unit -		Dictionary which describes LUN to be directly attached to VM: `address` - Address of the storage server. Used by iSCSI. `port` - Port of the storage server. Used by iSCSI. `target` - iSCSI target. `lun_id` - LUN id. `username` - CHAP Username to be used to access storage server. Used by iSCSI. `password` - CHAP Password of the user to be used to access storage server. Used by iSCSI. `storage_type` - Storage type either fcp or iscsi.
name -		Name of the disk to manage. Either `id` or `name`/`alias` is required. aliases: alias
nested_attributes - 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.
openstack_volume_type - added in 2.4		Name of the openstack volume type. This is valid when working with cinder.
poll_interval -	Default: 3	Number of the seconds the module waits until another poll request on entity status is sent.
profile -		Disk profile name to be attached to disk. By default profile is chosen by oVirt/RHV engine.
quota_id - added in 2.5		Disk quota ID to be used for disk. By default quota is chosen by oVirt/RHV engine.
shareable -		True if the disk should be shareable. By default when disk is created it isn't shareable.
size -		Size of the disk. Size should be specified using IEC standard units. For example 10GiB, 1024MiB, etc. Size can be only increased, not decreased.
sparse - added in 2.5		True if the disk should be sparse (also known as thin provision). If the parameter is omitted, cow disks will be created as sparse and raw disks as preallocated Note that this option isn't idempotent as it's not currently possible to change sparseness of the disk via API.
sparsify - added in 2.4		True if the disk should be sparsified. Sparsification frees space in the disk image that is not used by its filesystem. As a result, the image will occupy less space on the storage. Note that this parameter isn't idempotent, as it's not possible to check if the disk should be or should not be sparsified.
state -	Choices: present ← absent attached detached	Should the Virtual Machine disk be present/absent/attached/detached.
storage_domain -		Storage domain name where disk should be created. By default storage is chosen by oVirt/RHV engine.
storage_domains - added in 2.3		Storage domain names where disk should be copied. `IMPORTANT` There is no reliable way to achieve idempotency, so every time you specify this parameter the disks are copied, so please handle your playbook accordingly to not copy the disks all the time. This is valid only for VM and floating disks, template disks works as expected.
timeout -	Default: 180	The amount of time in seconds the module should wait for the instance to get into desired state.
upload_image_path - added in 2.3		Path to disk image, which should be uploaded. Note that currently we support only compatibility version 0.10 of the qcow disk. Note that you must have an valid oVirt/RHV engine CA in your system trust store or you must provide it in `ca_file` parameter. Note that there is no reliable way to achieve idempotency, so if you want to upload the disk even if the disk with `id` or `name` exists, then please use `force` true. If you will use `force` false, which is default, then the disk image won't be uploaded.
vm_id -		ID of the Virtual Machine to manage. Either `vm_id` or `vm_name` is required if `state` is attached or detached.
vm_name -		Name of the Virtual Machine to manage. Either `vm_id` or `vm_name` is required if `state` is attached or detached.
wait boolean	Choices: no yes ←	True if the module should wait for the entity to get into desired state.
