[ovirt-users] Getting error while trying to add VmPool using ovirtsdk4 version of the python api

Hello there, I am trying to add a VmPool to oVirt using the python ovirtSDK4 with following lines: I am omitting the import packages lines and connection lines. system_service = connection.system_service() vm_pools_service = system_service.vm_pools_service() templates_service = system_service.templates_service() clusters_service = system_service.clusters_service() tplist = templates_service.list(search='name=prueba') tpl=None biggest=-1 for t in tplist: ver = t.version if ver.version_number > biggest: biggest = ver.version_number tid = t.id tpl = t c = None for cluster in clusters_service.list(): if cluster.name == 'Pruebacluster': c = cluster pool = ovirtsdk4.types.VmPool(name='PRUEBA',size=1,type =ovirtsdk4.types.VmPoolType('manual'),template=tpl,cluster=c) vm_pools_service.add(pool=pool) I am getting the following error: Fault reason is "Request syntactically incorrect.". Fault detail is "For correct usage, see: https://ovirt.example.com/ovirt-engine/api/v4/model#services/vm-pools/met...;. HTTP response code is 400. I am a newbie in using this version of the API, suppose this is quite easy problem. Thanks for all the answers to come, Manuel
