Hi Shani, Thanks for your reply. I’m aware for how to set it in the UI. Note that because the VM is defined with Affinity label, I must first remove the affinity label from the VM and only than to choose a different host as you specified below (via the UI). But my question is for how to set a different host using Python SDK API. I tried/plan this via Python SDK API: - Stop the VM. - Remove its Affinity label. - Update its host to the target host. - Start the VM. But the result is that the VM is always keep starting on its current host. For updating the VM host, I used few ways as: vm_service.update( types.Vm( host=types.Host( id=host_id ), ) ) Or: vm_service.update( types.Vm( host=types.Host( name=host_name ), ) ) Then started the VM using: vm_service.start() or using: vm_service.start( vm=types.Vm( host=types.Host( name=host_name ), ) ) vm_service.start( vm=types.Vm( host=types.Host( id=host_id ), ) ) I get no errors, but VM keeps starting on the current host and not on the new target host. BTW - in case it would start on the target host, the plan is to add affinity label back just after.
