Hi,
It is working fine.
But I want to disable migration policy. It didn't solve my purpose.
What else I have to do to disable migration ?
Not sure what exactly you want to achieve. Can you elaborate a bit?
If in addition to pin the VM to a host you also want to disable
migration, you can use the Vm.placement_policy.affinity attribute:
vm = vms_service.add(
vm=types.Vm(
...
placement_policy=types.VmPlacementPolicy(
hosts=[
types.Host(name='host-01')
],
affinity=types.VmAffinity.PINNED
)
)
)
Martin, I think that you can explain better than me what are the
meanings of the values of the VmAffinity enum, and what is it
relationship to pinning. Would be nice to have that documented in the
specification of the API.

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')
]
)
)
)
