I have Centos 6.1 and i'm configuring cluster with conga, lucci and ricci these services are installed and running without problem. I need this type configuration for a high availability of virtual machines which is run on kvm. My problem is at the time of configuring "service group", when i click to add appears the new windows wich say "add service to cluster" and i fill the options (service named, run exclusive, failover domain, etc ) i can save this configuration and i dont have problem, but when after click to "add resource" option and appears "add to resource to service" and i select the option "virtual machine" i fill only the next option: Path to xmlfile used to create the VM -> /etc/libvirt/qemu/centos.xml VM configuration file path -> /etc/libvirt/qemu and after save the change appears the error in lucci: Error 500 We're sorry but we weren't able to process this request. And the lucci.log : Error - <type 'exceptions.AttributeError'>: 'Vm' object has no attribute 'delIndependentSubtree' URL: https://192.168.0.88:4443/cluster/machines/services_cmd?command=Edit File '/usr/lib/python2.6/site-packages/weberror/errormiddleware.py', line 162 in __call__ app_iter = self.application(environ, sr_checker) File '/usr/lib/python2.6/site-packages/tg/configuration.py', line 655 in wrapper return app(environ, start_response) File '/usr/lib/python2.6/site-packages/tg/configuration.py', line 555 in remover return app(environ, start_response) File '/usr/lib/python2.6/site-packages/repoze/tm/__init__.py', line 19 in __call__ result = self.application(environ, save_status_and_headers) File '/usr/lib/python2.6/site-packages/tw/core/middleware.py', line 43 in __call__ return self.wsgi_app(environ, start_response) File '/usr/lib/python2.6/site-packages/tw/core/middleware.py', line 68 in wsgi_app resp = req.get_response(self.application) File '/usr/lib/python2.6/site-packages/webob/__init__.py', line 1325 in get_response application, catch_exc_info=False) File '/usr/lib/python2.6/site-packages/webob/__init__.py', line 1293 in call_application app_iter = application(self.environ, start_response) File '/usr/lib/python2.6/site-packages/tw/core/resource_injector.py', line 68 in _injector resp = req.get_response(app) File '/usr/lib/python2.6/site-packages/webob/__init__.py', line 1325 in get_response application, catch_exc_info=False) File '/usr/lib/python2.6/site-packages/webob/__init__.py', line 1293 in call_application app_iter = application(self.environ, start_response) File '/usr/lib/python2.6/site-packages/beaker/middleware.py', line 73 in __call__ return self.app(environ, start_response) File '/usr/lib/python2.6/site-packages/beaker/middleware.py', line 152 in __call__ return self.wrap_app(environ, session_start_response) File '/usr/lib/python2.6/site-packages/routes/middleware.py', line 130 in __call__ response = self.app(environ, start_response) File '/usr/lib/python2.6/site-packages/pylons/wsgiapp.py', line 125 in __call__ response = self.dispatch(controller, environ, start_response) File '/usr/lib/python2.6/site-packages/pylons/wsgiapp.py', line 324 in dispatch return controller(environ, start_response) File '/usr/lib64/python2.6/site-packages/luci/controllers/root.py', line 48 in __call__ return BaseController.__call__(self, environ, start_response) File '/usr/lib64/python2.6/site-packages/luci/lib/base.py', line 48 in __call__ return TGController.__call__(self, environ, start_response) File '/usr/lib/python2.6/site-packages/pylons/controllers/core.py', line 221 in __call__ response = self._dispatch_call() File '/usr/lib/python2.6/site-packages/pylons/controllers/core.py', line 172 in _dispatch_call response = self._inspect_call(func) File '/usr/lib/python2.6/site-packages/pylons/controllers/core.py', line 107 in _inspect_call result = self._perform_call(func, args) File '/usr/lib/python2.6/site-packages/tg/controllers.py', line 857 in _perform_call self, controller, params, remainder=remainder) File '/usr/lib/python2.6/site-packages/tg/controllers.py', line 172 in _perform_call output = controller(*remainder, **dict(params)) File '/usr/lib64/python2.6/site-packages/luci/controllers/cluster.py', line 609 in services_cmd vret = validate_clusvc_form(self.model, **kw) File '/usr/lib64/python2.6/site-packages/luci/widget_validators/validate_resource.py', line 629 in validate_clusvc_form resObj.delIndependentSubtree() AttributeError: 'Vm' object has no attribute 'delIndependentSubtree' CGI Variables ------------- AUTH_TYPE: 'cookie' CONTENT_LENGTH: '-1' CONTENT_TYPE: 'application/x-www-form-urlencoded' HTTP_ACCEPT: 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' HTTP_ACCEPT_CHARSET: 'ISO-8859-1,utf-8;q=0.7,*;q=0.3' HTTP_ACCEPT_ENCODING: 'gzip,deflate,sdch' HTTP_ACCEPT_LANGUAGE: 'en-US,en;q=0.8,es-419;q=0.6,es;q=0.4' HTTP_CACHE_CONTROL: 'max-age=0' HTTP_CONNECTION: 'keep-alive' HTTP_COOKIE: 'tabCookie=0; expertMode=0; luci=ac68c9121cd1d044ebf15a2f2ec3db1252bb2ba7148b8328446d88a7323307db9627c40a; auth_tkt="63c7278294e41b63fce01b6af2eef3124f6b26ddroot!"'
