(Ah, Windows on ARM? Just kidding... :-)))))))

I think the name field is just a name, nothing else. And I use the config sample in this URL: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions#DomU_kernel_and_DTS

And this.

Make sure you have all Xen drivers complied in / loaded.
What do you mean "complied in / loaded"? And I follow the instruction listed in: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling.
And I copy the compiled xen-tools files to the dom0 image (root FS, or .img file) with:
# rsync -avp dist/install/ /mnt/

I'm still not clear why the system will halt when I type "xl list" or "xl create domU_config"?
