Error Hypervisor not running

Hi,
I am trying to install a virtual machine using Xen and getting this ‘error Hypervisor not running’ after I get the first page of adding a virtual machine.
Have I missed something?
My processor is good and I have the VXT running ok.

you must change your boot to the XEN Kernel and not the standard os boot Kernel.

Excuse me. I’n newbie in virtualization.
I just installed XEN Server, and when I try to boot from XEN kernel, I only get a text console of SUSE 11.0 (no desktop environment).
Is this OK? Or there are something wrong?

Thank you in advance.
