Good to see that people are trying out the new Xen support in mainline!

To boot under Xen you need to use a vmlinux / vmlinuz image.  Were you guys 
perhaps trying to use the bzImage?  That won't work (yet).

The vmlinux that's in the root of your kernel build tree ought to work.  I 
stripped and gziped mine to get a much, much smaller vmlinuz file and used it 
to boot a Xen domain for the first time last night - worked fine.

Mainline should support virtual block, virtual network, virtual console, SMP, 
etc but not live migration, suspend-resume, framebuffer, or anything 
involving dom0 functionality or direct device access.


Dave: Just a question. What use is a unicyle with no seat?  And no pedals!
Mark: To answer a question with a question: What use is a skateboard?
Dave: Skateboards have wheels.
Mark: My wheel has a wheel!
