    Unable to connect to xend error message : please help!!!


    We are using ksplice to perform upgrades on a dedicated server, running XEN vps. (QuickMachineSVM control panel)

    Since the last upgrade, we are no longer able to start any vps...

    if i do service xend status, i am getting : xend is running

    but if i try to start a virtual machine, by doing
    xm create vpsname.cfg, i am getting : Error: Unable to connect to xend: No such file or directory. Is xend running?

    What should i do to resolve this?

    I tried to boot using the old kernel, and i am getting the same problem!
