Hi,

I posted this thread a week ago under ovirt users: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/EJH2X5X5FDIR7Q7NTHOPYTNMOE3M6JDD/?sort=date

Maybe I posted on the wrong list. Anyway, I didn’t get any answer yet.

Hope you can help me here.

In short, I have a VM under Cluster Affinity label. And need to cold migrate this VM to another host.

For that, I’m doing this (Via Python REST API):

• Stop the VM.
• Remove its Affinity label.
• Update its host to the target host.
• Start the VM.

But the result is that the VM is always keep starting on its current host.

For updating the VM host, I used few ways as:

vm_service.update(

                types.Vm(

                                host=types.Host(

                                    id=host_id

                    ),

    )

)

Or:

vm_service.update(

                types.Vm(

                                host=types.Host(

                                    name=host_name

                    ),

    )

)

Then started the VM using:

vm_service.start()

or using:

vm_service.start(

    vm=types.Vm(

            host=types.Host(

                                                                name=host_name

                                                ),

        )

)

vm_service.start(

    vm=types.Vm(

            host=types.Host(

                                                                id=host_id

                                                ),

        )

)

I get no errors, but VM keeps starting on the current host and not on the new target host.

BTW – in case it would start on the target host, the plan is to add affinity label back just after.
