I am not a HIPL developer anymore (hopefully the current developers can
answer better soon), but I think the kernel and the kernel patches HIPL
provides do not have UML support by default. You might need a separate UML
patches for the corresponding kernel. "make xconfig" (without ARCH=um) for
normal processors should work fine.
The solution is to test HIPL in a real host or see if there are UML
patches available for the corresponding kernel and see if it can be
applied successfully to the HIPL kernel.
