Parameters 

Parameter	Comments
activate boolean	True if the disk should be activated. When creating disk of Virtual Machine it is set to True. Choices: `false` `true`
auth dictionary / required	Dictionary with values needed to create HTTP/HTTPS connection to oVirt:
ca_file string	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.
compress boolean	Flag indicating if compression is used for connection. Choices: `false` `true` ← (default)
headers dictionary	Dictionary of HTTP headers to be added to each API call.
hostname string	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.
insecure boolean	A boolean flag that indicates if the server TLS certificate and host name should be checked. Choices: `false` ← (default) `true`
kerberos boolean	A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication. Choices: `false` `true`
password string	The password of the user. Default value is set by `OVIRT_PASSWORD` environment variable.
timeout integer	Number of seconds to wait for response.
token string	Token to be used instead of login with username/password. Default value is set by `OVIRT_TOKEN` environment variable.
url string	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.
username string	The name of the user, something like admin@internal. Default value is set by `OVIRT_USERNAME` environment variable.
backup string added in ovirt.ovirt 1.1.0	The backup behavior supported by the disk. Choices: `"incremental"`
bootable boolean	True if the disk should be bootable. By default when disk is created it isn’t bootable. Choices: `false` `true`
content_type string	Specify if the disk is a data disk or ISO image or a one of a the Hosted Engine disk types The Hosted Engine disk content types are available with Engine 4.3+ and Ansible 2.8 Choices: `"data"` ← (default) `"iso"` `"hosted_engine"` `"hosted_engine_sanlock"` `"hosted_engine_metadata"` `"hosted_engine_configuration"`
description string	Description of the disk image to manage.
download_image_path string	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	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`. Choices: `false` ← (default) `true`
force boolean	Please take a look at `image_path` documentation to see the correct usage of this parameter. Choices: `false` ← (default) `true`
format string	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. Choices: `"raw"` `"cow"` ← (default)
host string	When the hypervisor name is specified the newly created disk or an existing disk will refresh its information about the underlying storage( Disk size, Serial, Product ID, Vendor ID …) The specified host will be used for gathering the storage related information. This option is only valid for passthrough disks. This option requires at least the logical_unit.id to be specified
id string	ID of the disk to manage. Either `id` or `name`/`alias` is required.
image_provider string	When `state` is exported disk is exported to given Glance image provider. When `state` is imported disk is imported from 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 string	Driver of the storage interface. It’s required parameter when creating the new disk. Choices: `"virtio"` `"ide"` `"sata"` `"virtio_scsi"`
logical_unit dictionary	Dictionary which describes LUN to be directly attached to VM:
address string	Address of the storage server. Used by iSCSI.
lun_id string	LUN id.
password string	CHAP Password of the user to be used to access storage server. Used by iSCSI.
port string	Port of the storage server. Used by iSCSI.
storage_type string	Storage type either fcp or iscsi.
target string	iSCSI target.
username string	CHAP Username to be used to access storage server. Used by iSCSI.
max_workers integer added in ovirt.ovirt 1.7.0	The number of workers which should be used in the upload/download of the image. The use of multiple workers can speed up the process.
name aliases: alias string	Name of the disk to manage. Either `id` or `name`/`alias` is required.
nested_attributes list / elements=string	Specifies list of the attributes which should be fetched from the API. This parameter apply only when `fetch_nested` is true.
openstack_volume_type string	Name of the openstack volume type. This is valid when working with cinder.
pass_discard boolean added in ovirt.ovirt 1.2.0	Defines whether the Virtual Machine passes discard commands to the storage. Choices: `false` `true`
poll_interval integer	Number of the seconds the module waits until another poll request on entity status is sent. Default: `3`
profile string	Disk profile name to be attached to disk. By default profile is chosen by oVirt/RHV engine.
propagate_errors boolean added in ovirt.ovirt 1.2.0	Indicates if disk errors should cause Virtual Machine to be paused or if disk errors should be propagated to the the guest operating system instead. Choices: `false` `true`
quota_id string	Disk quota ID to be used for disk. By default quota is chosen by oVirt/RHV engine.
read_only boolean	True if the disk should be read_only. By default when disk is created it isn’t read_only. Choices: `false` `true`
scsi_passthrough string added in ovirt.ovirt 1.2.0	Indicates whether SCSI passthrough is enable and its policy. Setting a value of `filtered`/`unfiltered` will enable SCSI passthrough for a LUN disk with unprivileged/privileged SCSI I/O. To disable SCSI passthrough the value should be set to `disabled` Choices: `"disabled"` `"filtered"` `"unfiltered"`
shareable boolean	True if the disk should be shareable. By default when disk is created it isn’t shareable. Choices: `false` `true`
size string	Size of the disk. Size should be specified using IEC standard units. For example 10GiB, 1024MiB, etc. Size can be only increased, not decreased. If the disk is referenced by `name` and is attached to a VM, make sure to specify `vm_name`/`vm_id` to prevent extension of another disk that is not attached to the VM.
sparse boolean	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. Choices: `false` `true`
sparsify boolean	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. Choices: `false` `true`
state string	Should the Virtual Machine disk be present/absent/attached/detached/exported/imported. Choices: `"present"` ← (default) `"absent"` `"attached"` `"detached"` `"exported"` `"imported"`
storage_domain string	Storage domain name where disk should be created.
storage_domains list / elements=string	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 integer	The amount of time in seconds the module should wait for the instance to get into desired state. Default: `180`
upload_image_path aliases: image_path string	Path to disk image, which should be uploaded. Note if `size` is not specified the size of the disk will be determined by the size of the specified image. 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. Note that in order to upload iso the `format` should be ‘raw’.
uses_scsi_reservation boolean added in ovirt.ovirt 1.2.0	Defines whether SCSI reservation is enabled for this disk. Choices: `false` `true`
vm_id string	ID of the Virtual Machine to manage. Either `vm_id` or `vm_name` is required if `state` is attached or detached.
vm_name string	Name of the Virtual Machine to manage. Either `vm_id` or `vm_name` is required if `state` is attached or detached.
wait boolean	`yes` if the module should wait for the entity to get into desired state. Choices: `false` `true` ← (default)
wipe_after_delete boolean	If the disk’s Wipe After Delete is enabled, then the disk is first wiped. Choices: `false` `true`
