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

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/place... 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') ] ) ) )
Thanks will try and let you know, ~Rohit On Wed, Apr 19, 2017 at 1:18 PM, Juan Hernández <jhernand@redhat.com> wrote:

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 On Wed, Apr 19, 2017 at 1:36 PM, TranceWorldLogic . < tranceworldlogic@gmail.com> wrote:

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 Juan, It working fine. affinity and hosts have solved my problem. Thanks, ~Rohit On Wed, Apr 19, 2017 at 5:16 PM, Juan Hernández <jhernand@redhat.com> wrote:
