OVM Server login through xml-rpc

Question

Hi,
I installed OVM Server 2.2.1 on a x86 pc. Interested in remote control of OVM through xml-rpc, I try to login through xml-rpc. The python codes which are referenced from Xen API are:
*>>> import xmlrpclib*
*>>> server = xmlrpclib.Server("http://mypc:8006")*
*>>> session = server.session.login_with_password("xxxx", "xxxx")*
The OVM Server can't be login. The error message is:
*{'Status': 'Failure', 'ErrorDescription': ['MESSAGE_METHOD_UNKNOWN', 'session.login_with_password']}*
I have modified /etc/xen/xend-config.sxp as follows before login:
*1. (xend-tcp-xmlrpc-server yes)*
*2. (xend-tcp-xmlrpc-server-address 'mypc')*
*3. (xend-tcp-xmlrpc-server-port 8006)*
Then I restart xend.
OVM Server support xml-rpc, since the communication between OVM Server and Manager is through xml-rpc. From feedback error message, the socket communciation is OK. I wonder whether xmlrpclib is modified, or the question lies on password and username?
Thanks for any help.

Hi,
I would not mess around with xml-rpc, because the calls are not documented by Oracle.
So if you change the OVS_AGENT/MANAGER it might be, that these calls change.
As an alternative I would suggest either taking the web-service API, which the OVM Manager provides, or use ovmcli, if you prefer the commandline.
