Not too familiar with this, but maybe this example will help[1]

Hi Shani,

Thanks for your reply. I’m aware for how to set it in the UI.
Note that because the VM is defined with Affinity label, I must first remove 
the affinity label from the VM and only than to choose a different host as you 
specified below (via the UI).
But my question is for how to set a different host using Python SDK API.

I tried/plan this via Python SDK 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.

Thanks,
Lavi Buchnik

Hi,
You can set this one from the UI:
VM > Edit > Show advanced options (bottom left button) > host > Start running 
on > specific host
