I am confused. Just try to reproduce :-
with .config i've sent to you yesterday.

I believe Konrad wrote you the same.
You mix several sources. I wouldn't do that.

Yup. I would suggest you add 'console=hvc0' so you can see the output.

Yes. But from your /boot/grub/menu.lst it looks that you do have the
xen-3.5.gz compiled?

No , this is just the copy-paste from
I don't have the xen-3.5.gz  compiled . (just for my understanding )
Neither do i know how to compile it
for the pvops kernel ( that I am using.
Can you shed some light as to how I can generate the xen.gz image , Please note that
I have CONFIG_XEN_DOM0=y set in my .config file.
I have attached the .config and menu.lst file for your reference.

What is the significance of   CONFIG_XEN_DOM0=y ? does is generate
dom0 image as well ? If yes where ??

Thanks anyways for your concern.

For details on how to do that look at the URL that
Boris sent - it is pretty comprehensive.

Also take a look at this (which Boris wrote as well):

That explains how to setup the GRUB2 entry correctly.

Boris, I am CC-ing you on this e-mail. Any suggestions on what else he
might need to do?
