      I am stuck with the above error ... trying to setup Oracle VM using OVMM 3.2.7.

       

      Could you please advice ?

       

       

      1. A fix for the above error ...

           if not ...

       

      2. The way to delete OVM Server from OVMM 3.2.7 ....

          Can you elaborate more on the setup? What are you trying to install? Oracle VM Manager or Oracle VM Server? On what platform?

            Did you get a solution to your error?

             

            I am running into a same error being reported when I try to add a new repository, with 3.2.8.  Had no issues with 3.2.7.

             

            In summary:

            • Installed new OVM Server 3.2.8 , with local storage.
            • Installed new OVM Manager 3.2.8
            • Can Discover the new Server without any issues

             

            But any attempt to create a repository just hangs, via the GUI and using the CLI

             

            Via CLI, following steps were followed:

             

            1.  Identify the local physical disk using the: OVM> list physicaldisk

            2.  Run this command to create the repository:  OVM> create Repository name=irisRepo1 serverPool=dbvpool01 physicalDisk=0004fb00001800000180575261fd1842

                 It just sits there, with no feedback, and times out the CLI session.



            Looking at the OVM Server I can see the following in the /var/log/ovs-agent.log

            ..

            ..

             


            I have restarted the ovs-agent on the server, still same behaviour.

            Nothing happens and I have to abort the job under the manager job tab.


            Any ideas?

              In addition to previous update, I have double checked, all firewall (iptables) are shutdown between these two servers so there is not firewall blocking anything.

              Even restarted the OVM server, still same issue.

              I have a second server, identical and was able to create a repository on it using the same CLI method posted earlier.

              But with this server,I keep getting same messages as previous update with notification errors and "..Unable to send notification: (2, 'No such file or directory')"

                Well it looks like something is missing in /usr/lib/python2.4/site-packages

                Compared and there seem to have been one missing directory - /usr/lib/python2.4/site-packages/com

                Strange as this was a clean install.

                I guess a reinstall would have fixed it, but I just copied contents from another OVM server with exact same install and now it works...
