[Xen-users] about xen xmlrpc-tcp-server

["pine_tan" <pine_tan@xxxxxxx>]

Hi all,

 

    Now I have some questions about the xen's xmlrpc-tcp server and XenMan's remote management.

 

    Q1. I have modified the /etc/xen/xend-config.sxp as follows:

        (xend-tcp-xmlrpc-server yes)

        (xen-tcp-xmlrpc-server-address 'localhost')
        (xen-tcp-xmlrpc-server-port 8006)

        (xend-address '')

 

        So I have open the xmlrpc-tcp server, and I can get correct result with "netstat -a|grep 8006".

        If I use "telnet localhost 8006", it is ok. It gives me the information as follows:

 

        Try 127.0.0.1...

        Connected to localhost.localdomain (127.0.0.1)

        Escape character is '^]'

 

        But if I want to use "telnet 172.19.11.14 8006" (assumed my machine's IP is 172.19.11.14 ), it is error:

 

        Trying 172.19.11.14...

        telnet: connect to address 172.19.11.14: Connection refused

        telnet: Unable to connect to remote host: Connection refused

 

        Why? Because of authentication? Or else?

 

  Q2. In /etc/xen/xend-config.sxp, there are

        #(xend-tcp-xmlrpc-server-ssl-key-file  /etc/xen/xmlrpc.key)
        #(xend-tcp-xmlrpc-server-ssl-cert-file /etc/xen/xmlrpc.crt)

 

        Is it implies that xend use ssh as its xmlrpc server's connection protocol?

        Can change it to traditional telnet protocol, though telnet is not security?

 

  Q3: I am trying XenMan v0.6 to manage remote xen hosts, but I meet some problems.

        When I use xenman to connect remote host, it always tell me that

        no element fount: line 1, column 0

 

        I try to debug the source code, exception are

         File "/usr/lib/python2.4/xmlrpclib.py", line 527, in feed

           self._parse.Parse(data,0)

 

       I debug XenNode.py separately

......

 

if __name__ == "__main__":

    host = "172.19.11.14"

    username = 'root'
    passwd = 'XXX'
    
    managed_node = XenNode(hostname=host,
                           username = username,
                           password = passwd,
                           isRemote=remote)

 

   managed_node.refresh()

 

   And it can get the correct result.

   Moreover, I have added some debug code in remote host's xend source code,

   remote xend always can give the ecorrect domains' information.

   But why I cannot get correct one?

 

   I use CentOS 5, Python 2.4, Xen 3.1 Paramiko 1.7.1, pycrypto-2.0.1

 

Q4: Can I use normal telnet while not ssh as XenMan's connection protocol? If Xen allow that.

 

 

 

How can I solve the problems?

 

   Thanks a lot.
