Ok, so dropping back a step. Let's assume that I build the 3.2.0 XEN
hypervisor and dom0 kernel using 2.6.18 as base. I should then be able to
build domU kernel(s) using the linux-source-2.6.25 files? How?
I can't seem to get CONFIG_XEN set in my .config file. Running "make
menuconfig" does not show any xen-specific options.
