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 ,
),
)
