Hello, I am trying to create a virtual machine from a template using oVirt API. Somehow like this: --- def createVM(connection, cluster, vmname, vmtemplate): try: param = params.VM( name=vmname, \ cluster=connection.clusters.get(name=cluster), \ template=connection.templates.get(name=vmtemplate), \ use_latest_template_version = True ) except: print "Could not construct a request to oVirtapi,please check parameters which were being sent to" return None try: connection.vms.add(param) except: print "I was not able to commit my request into oVirt api." return None return "OK" --- Everything is fine when I have only ONE version of a template. But I am used to create several number of versions for one template because it is quite flexible. In this case, when I run my script, I receive an "AmbiguousQueryError" error even if an option "use_latest_template_version = True" is used. I revised file /usr/lib/python2.7/site-packages/ovirtsdk/utils/filterhelper.py and found near line 30 that this error is raised unquestionably: -- if len(result) > 1: raise AmbiguousQueryError(query) return result[0] if result else None -- It seems quite strange. Either I do not understand the meaning of option "use_latest_template_version" or using of this option does not make sense, I mean query constructed in params.VM() function will not be passed by filterhelper.py in current implementation. I made a small patch that allows me to use the latest version of the template during VM creation: -- if len(result) > 1 : result = result[len(result) - 1] return result #raise AmbiguousQueryError(query) return result[0] if result else Nonepython-2.7.5-34.el7.x86_64 -- But I am still not sure that original behaviour of filehelper.py is unexpectable. I would be very pleasant if you explain me this issue. My OS is CentOS 7. I use Python python-2.7.5-34.el7.x86_64. Version of ovirt-engine-sdk is ovirt-engine-sdk-python-3.6.8.0-1.el7.centos.noarch -- Thanks in advance, Roman A. Chukov. https://asgardahost.org
