The Vm.host attribute is used only to indicate in what host is the VM
currently running.

To pin the VM to a set of hosts you have to use Vm.placement_policy, as
described here:


http://ovirt.github.io/ovirt-engine-api-model/4.1/#types/vm/attributes/placement_policy

With the Python SDK it should be something like this:

  vm = vms_service.add(
    vm=types.Vm(
      ...
      placement_policy=types.PlacementPolicy(
        hosts=[
          types.Host(name='host-01')
        ]
      )
    )
  )
