Hello list!
I have been trying to rename a disk alias that defaults to
"some_template_name-Disk1" to something more logical by using ovirtsdk4 (in my
example to "vm2_disk_0"). On the list itself, I saw a couple of examples for
older version of SDK. Basically, I am trying to create a VM and then update its
properties, notably "alias" attribute that can be found in types.Disk. The first
portion of the code works well (vm provisioning), but second one (alias update) does not,
causing the TypeError exception. Obviously, I am doing something wrong here. I have spent
most of the time trying to figure out how to actually do this. I would kindly ask for some
hint.
Thank you in advance!
Regards,
Branimir

# create a vm

# update the vm in terms of disk name
vm = vms_service.list(search='name=vm2')[0]
vm_service = vms_service.vm_service(vm.id)
updated_vm = vm_service.update(
types.Vm(
disk_attachment = types.Disk(alias='vm2_disk_0')
)
)

Try to update the DiskAttachment:
vm = vms_service.list(search='name=NFSVM')[0]
disk_attachments_service = vms_service.vm_service(vm.id
).disk_attachments_service()
#here I take the first one, works because I have only one disk
disk_attachment = disk_attachments_service.list()[0]
disk_attachment_service = disk_attachments_service.attachment_service(
disk_attachment.id)
disk_attachment_service.update(
types.DiskAttachment(
disk=types.Disk(
name='NewDiskName',
),
),
)

Hi Fred!
Thank you very much for your help! It is working!
I only added the following (as suggested in
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/...;
page 12) in order to wait for a vm to go from "image locked" to "down"
state.
vm_service = vms_service.vm_service(vm.id)
while True:
time.sleep(5)
vm_s = vm_service.get()
if vm_s.status == types.VmStatus.DOWN:
break
Thank you once more!
Regards,
Branimir
