OK.
Just remember that newer Xen versions support older kernels.. backwards
compatibility. But not the other way around..
If your kernel is compiled for Xen 3.0.3, it will work under Xen 3.1.0.
But if your kernel is compiled for Xen 3.1.0, it wont work with Xen 3.0.3.

You know you don't have to use virt-manager.. :)
Just use the cmdline tools and create your own configuration file for domU..
that way you know for sure what you get and how.

You should ask from Pardus guys/lists.. I don't what they support/require.
What happens when you boot your domU with Pardus kernel? Is it PV domU? Are
you using pygrub?
