[Users] python-sdk : how to modify a vm to "Run on" a "Specific" host and set "Migration Options

[karthik S]

Hi Michael Pasternak,

Thanks for the info.

I was able to modify the VM as :

        vm_placement_params = params.VmPlacementPolicy(host =
params.VM(name=rhev_host_name),  affinity = "pinned")
        vm_obj.set_placement_policy(vm_placement_params)
        vm_obj.update()


Thanks much !!

thanks,
Karthik
