Re: [ovirt-users] create a cloned virtual machine based on a template with SDK API python

Hi, I want to create a cloned virtual machine based on a template with SDK API python and i don't find the parameter to indicate the clone action for the disk here is my code : #!/usr/bin/env python # -*- coding: utf-8 -*- # # Copyright (c) 2016 Red Hat, Inc. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. # from pprint import pprint import logging import time import ovirtsdk4 as sdk import ovirtsdk4.types as types template_name='test_debian_9.4' template_version=1 cluster_name='nico-cluster' data_domain_name='OVIRT-TEST2' logging.basicConfig(level=logging.DEBUG, filename='example.log') # This example will connect to the server and start a virtual machine # with cloud-init, in order to automatically configure the network and # the password of the `root` user. # Create the connection to the server: connection = sdk.Connection( url='https://ocenter.province-sud.prod/ovirt-engine/api', username='admin@internal<mailto:username='admin@internal>', password='admin', ca_file='CA_ocenter.pem', debug=True, log=logging.getLogger(), ) ################################## ############ TEMPLATE ############ ################################## # Get the reference to the root of the tree of services: system_service = connection.system_service() # Get the reference to the service that manages the storage domains: storage_domains_service = system_service.storage_domains_service() # Find the storage domain we want to be used for virtual machine disks: storage_domain = storage_domains_service.list(search='name='+data_domain_ name)[0] # Get the reference to the service that manages the templates: templates_service = system_service.templates_service() # When a template has multiple versions they all have the same name, so # we need to explicitly find the one that has the version name or # version number that we want to use.

The selected Storage Domain does not contain the VM Template.]". HTTP response code is 400. So how to create a cloned virtual machine based on a template ? I think i'm looking for the same parameter on the web ui, "Storage Allocation" => Thin/Clone [cid:1521702568.14216.1.camel@province-sud.nc] Thanks.
