I have CPU with virtualization extensions just looked inside the bios.
It an intel 2.16 dual core 2.

I wanted to just add the xen extension to my own modified laptop kernel.

Compared to xen it has VGA_POST + X86EMU for suspend resume to work, 
also it VM86, can remember why now.

It config'ed, but failed under make (make depend also succesful).

Luckily there is a holiday coming on, so i might have some sime to look 
into it next week, to see if there are some conflicting stuff in there 
or if i missed something else(to add).

Just including xen3 kernel part, (which includes xen2_dom0)
errored with multiple defined options.

Anyways does anyone know why there isn't a XEN3|2_DOM0 with PAE, not 
neceessary?.
trying to add options pae, just created an error.

As you can see i just tried some things out, i havent had the time yet 
to really look into to how everything works yet.

(but i do know how to boot an alternative kernel;))
