Your kernel version should contain -xen

Can you paste the output from 'uname'

Verify that you booted a xen kernel, cuz the steps you followed do not include copy the kernel to /boot neither checking grub.

Thank you very much for your reply.

Kernel version => 2.6.18.8
OS => Linux
configuration file is attached.

Steps I followed :

make world
make install
copy initrd image to /boot/
reboot
Is there any xend configuration needed ?
Is there any dom0 configuration needed ??


Please help me to get through this.

Leena

Some more info might be useful like:

 - Your kernel version
 - The OS you are running
 - Xen version that is installed
 - etc..

It looks like you did not boot into a xen-kernel, but it might be too early to tell.
At least this line is suspicious:

"[2010-03-16 05:22:34 1656] DEBUG (XendDomain:387) number of vcpus to use is 0"

Give some more info an we might be able to help you.
