Os environment is ubuntu12.04
i install xen by the commond apt-get install xen-hypervisor-4.1-amd64, during the installation, a wired message "No volume groups found" appears.
When i create vm, it fails with the message "Unable to connect to xend: Connection refused. Is xend running?". Howerver the commod "xm list" works and i'm sure service xend has started already.

    I'm no expert by any means, but this looks like the installation cannot find the volume group for storage. If that's the case, any number of problems might occur.

    Let me see if I can find someone with a better handle on the details of this problem.

    Received the following from Lars Kurth, Xen Project Community Manager:

    https://help.ubuntu.com/community/Xen outlines how to install Xen on Ubuntu (see "During installation of Ubuntu"). Also http://www.virtuatopia.com/index.php/Building_a_Xen_Virtual_Guest_Filesystem_using_Logical_Volume_Management_(LVM), gives a good overview on disk management and Xen.

    My inderstanding is that the "Unable to connect to xend: Connection refused. Is xend running? error does typicall occur when the Dom0 volume is full (or maybe in this case does not exist, because xenlearner forgot to set up an empty volume group). There are quite a few articles out there when you google for the error message.

    So the issue does indeed appear to be the lack of a usable volume group. I suggest you examine the links above to see if they give you the information you need to correct the situation. If not, ask for more information here or in the xen-users mailing list.

    Let us know how it goes!
