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.

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 ?

Thanks,
~Rohit

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')
]
  )
)
  )

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')
]
  )
)

[ovirt-users] [Python-SDK][Ovirt-4.0] Create VM on specific Host.

[TranceWorldLogic .]

Hi,

I was trying to create VM on specific HOST using python sdk as shown below.

-- Code ---
vm = vms_service.add(  
host = types.Host(
name = "host-01",
),
  )
-- End Code ---

It created VM successfully, but when I see in ovirt GUI I saw that VM is
not bonded with specific host.

Ovirt GUI:
Virtual Machines -> click on VM -> "Edit" button -> In advance menu ->
"Host" tab
Start Running On:
   o  Any Host in Cluster  <== This option got selected
   o  Specific Host(s)   <== *I want this option to select.*

Please help me to bind VM to specific Host via Python SDK

Thanks,
~Rohit
