Although the nested kernels (with properly configured CONFIG_NEST_LEVEL) booted properly and appeared to work well, it ran into trouble (i.e., seg faults and/or hangs) whenever I tried to ssh into one of the nested kernels. When I find some free time, I'll try it again with the latest UML kernels and report any successes or failures.
