I am able to monitor the VMs on the local host , but it fails for the remote machine. XenMan. Using netsat -tan , I monitored that managed system listens on 8006 , but XenMan by default connects at 8005 on system XenMan is used to manage other remote machine VMs I tested it also changing the the managing system Port from 8005 to 8006 Following log is generated in the XenMan side When Managed Server Port 8006 Client (Managing Xen Port) 8005 setting last_error [Error 0], [open_channel]Connect failed setting last_error [Error 0], [open_channel]Connect failed setting last_error [Error 0], [open_channel]Connect failed Traceback (most recent call last): File "src/xenman.py", line 2493, in wrapper funct(widget, *args, **cargs) File "src/xenman.py", line 2385, in start_all_domains domains = managed_node.get_dom_names() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 125, in get_dom_names return self.dom_list.iterkeys() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 378, in iterkeys return self.dom_dict.keys() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 311, in __getattr__ return self._init_dom_list() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 306, in _init_dom_list self.refresh() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 317, in refresh dom_list_info = self.node.node_proxy.xend.domains(1) File "/root/XenMan_Installs/xenman-0.6/src/XenServerProxy.py", line 165, in __call__ ret = self.__send(self.__name, args) File "/usr/lib/python2.4/site-packages/xen/util/xmlrpclib2.py", line 122, in __request response = xmlrpclib.ServerProxy.__request(self, methodname, params) File "/usr/lib/python2.4/xmlrpclib.py", line 1383, in __request verbose=self.__verbose File "/root/XenMan_Installs/xenman-0.6/src/XenServerProxy.py", line 133, in request return Transport.request(self, host, '/RPC2', request_body, verbose) File "/usr/lib/python2.4/xmlrpclib.py", line 1129, in request self.send_content(h, request_body) File "/usr/lib/python2.4/xmlrpclib.py", line 1243, in send_content connection.endheaders() File "/usr/lib/python2.4/httplib.py", line 798, in endheaders self._send_output() File "/usr/lib/python2.4/httplib.py", line 679, in _send_output self.send(msg) File "/usr/lib/python2.4/httplib.py", line 646, in send self.connect() File "/root/XenMan_Installs/xenman-0.6/src/XenServerProxy.py", line 84, in connect ("localhost",self.localport)) File "/root/XenMan_Installs/xenman-0.6/src/phelper.py", line 326, in open_channel raise CommunicationException(0, "[open_channel]" +str(ex)) CommunicationException: [Error 0], [open_channel]Connect fail The below fragment is generated when I changed the Xen port to 8006 on the managing system side. got expat error no element found: line 1, column 0 Traceback (most recent call last): File "src/xenman.py", line 2493, in wrapper funct(widget, *args, **cargs) File "src/xenman.py", line 2469, in connect_node names = managed_node.get_dom_names() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 125, in get_dom_names return self.dom_list.iterkeys() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 378, in iterkeys return self.dom_dict.keys() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 311, in __getattr__ return self._init_dom_list() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 306, in _init_dom_list self.refresh() File "/root/XenMan_Installs/xenman-0.6/src/XenNode.py", line 317, in refresh dom_list_info = self.node.node_proxy.xend.domains(1) File "/root/XenMan_Installs/xenman-0.6/src/XenServerProxy.py", line 165, in __call__ ret = self.__send(self.__name, args) File "/usr/lib/python2.4/site-packages/xen/util/xmlrpclib2.py", line 122, in __request response = xmlrpclib.ServerProxy.__request(self, methodname, params) File "/usr/lib/python2.4/xmlrpclib.py", line 1383, in __request verbose=self.__verbose File "/root/XenMan_Installs/xenman-0.6/src/XenServerProxy.py", line 133, in request return Transport.request(self, host, '/RPC2', request_body, verbose) File "/usr/lib/python2.4/xmlrpclib.py", line 1147, in request return self._parse_response(h.getfile(), sock) File "/usr/lib/python2.4/xmlrpclib.py", line 1284, in _parse_response p.close() File "/usr/lib/python2.4/xmlrpclib.py", line 530, in close self._parser.Parse("", 1) #
