I've sent following example to our Python SDK,
feel free to try and review:

Also you may checkout relevant Ansible module, which support this
functionality as well:

I am trying to add direct LUN disk to a VM with python ovirtsdk4 ( storage domain is iscsi ) .
Adding a COW disk is working as in the SDK example, attached below, i have tried different things that i saw online but did not work, anybody have an example of how to add a direct LUN disk ?

def add_VM_disk(self):

vms_service = self.connection.system_service().vms_service()
vm = vms_service.list(search='name=myvm')[0]

# Locate the service that manages the disk attachments of the virtual
# machine:
disk_attachments_service = vms_service.vm_service(vm.id).disk_attachments_service()

# Use the "add" method of the disk attachments service to add the disk.
# Note that the size of the disk, the `provisioned_size` attribute, is
# specified in bytes, so to create a disk of 10 GiB the value should
# be 10 * 2^30.
disk_attachment = disk_attachments_service.add(
types.DiskAttachment(
disk=types.Disk(
name='mydisk',
description='My disk',
format=types.DiskFormat.COW,
provisioned_size=10 * 2 ** 30,
),
interface=types.DiskInterface.VIRTIO,
bootable=False,
active=True,
),
)
