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/pl...
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')
]
)
)
)
Sorry, the name of the type is incorrect, should be
'types.VmPlacementPolicy'. So the complete example should be like this:
vm = vms_service.add(
vm=types.Vm(
...
placement_policy=types.VmPlacementPolicy(
hosts=[
types.Host(name='host-01')
]
)
)
)
