Parameters

Parameter Choices/Defaults Comments

    Choices:
  • no

True if the disk should be activated.
When creating disk of virtual machine it is set to 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.

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
    Choices:
  • no
  • yes
A boolean flag that indicates if the server TLS certificate and host name should be checked.
kerberos
boolean
    Choices:
  • no
  • yes
A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication.
password
string / required
The password of the user.
Default value is set by OVIRT_PASSWORD environment variable.
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 / required
The name of the user, something like admin@internal.
Default value is set by OVIRT_USERNAME environment variable.
bootable
boolean
    Choices:
  • no ←
  • yes
True if the disk should be bootable. By default when disk is created it isn't bootable.
content_type
-
added in 2.8
    Choices:
  • data ←
  • iso
  • hosted_engine
  • hosted_engine_sanlock
  • hosted_engine_metadata
  • hosted_engine_configuration
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
description
-
added in 2.5
Description of the disk image to manage.
download_image_path
-
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
    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
boolean
    Choices:
  • no
  • yes
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.
host
-
added in 2.8
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
-
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.
lun_id
-
LUN id.
password
-
CHAP Password of the user to be used to access storage server. Used by iSCSI.
port
-
Port of the storage server. Used by iSCSI.
storage_type
-
Storage type either fcp or iscsi.
target
-
iSCSI target.
username
-
CHAP Username to be used to access storage server. Used by iSCSI.
name
-
Name of the disk to manage. Either id or name/alias is required.

aliases: alias
nested_attributes
list
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
integer
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
boolean
    Choices:
  • no
  • yes
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
boolean
added in 2.5
    Choices:
  • no
  • yes
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
boolean
added in 2.4
    Choices:
  • no
  • yes
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
  • exported
Should the Virtual Machine disk be present/absent/attached/detached/exported.
storage_domain
-
Storage domain name where disk should be created.
storage_domains
-
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
Default:
180
The amount of time in seconds the module should wait for the instance to get into desired state.
upload_image_path
-
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 to upload iso the format should be 'raw'
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 ←
yes if the module should wait for the entity to get into desired state.
wipe_after_delete
boolean
    Choices:
  • no
  • yes
If the disk's Wipe After Delete is enabled, then the disk is first wiped.
