    hi friends,,
    i hav used the HOWTO in this link http://www.howtoforge.com/installing-xen-3.3-with-kernel-2.6.27-on-ubuntu-8.10-x86_64..

    However i get the following error when i type "xm create /etc/xen/xen1.example.com.cfg"

    ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
    Traceback (most recent call last):
    File "/usr/sbin/xm", line 8, in <module>
    from xen.xm import main
    File "/usr/lib/python2.5/site-packages/xen/xm/main.py", line 61, in <module>
    xc = xen.lowlevel.xc.xc()
    xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

    i hope i shall get the problem here.

    Did you boot into the Xen kernel? It seems as if Xen is not running.

    What's the output of
    Code:
    uname -a
    ?

    Hi friend,,
    thanks for the prompt reply..But unfortunatly i`m away from the computer now..However is shall provide u the output of that "Uname" command by tommrrow.
    but here i wantd to ask a question..
    when i follwed thta "HOW TO" ..it prompted me to install Xen thro internet and i did ..How ever when i rebooted the computer..there was no xen on grub..instead there was "UBUNTU server" on my ubuntu 8.10 desktop computer..

    Thanks

    That's the normal Ubuntu kernel which cannot be used for a Xen dom0.

    What's the output of
    Code:
    ls -la /boot
    , and what's in /boot/grub/menu.lst?

    There's an initrd.img for kernel 2.6.27, but no vmlinuz or config file for that kernel which makes me believe it wasn't installed properly. Did you see any errors during the installation of that kernel?

    What's in /boot/grub/menu.lst?

    No signs of a Xen kernel. There must have gone something wrong when you tried to build the kernel.
