As I said in my other reply, "what's wrong" is that the patch referenced has not (yet) been incorporated in the kernel that ships with SLES. The developerWorks web site is intended for people that intend to build their own kernel from source. That means, distribution providers, or people who are doing it for educational or other purposes. In your case, you should go with the manual procedure that gives all the z/VM commands to use. Understand, though, that the resulting kernel-in-NSS is not (yet) supported by Novell. If/when we ship that functionality, it will be supported. Until then, you're on your own unless you are willing to negotiate a custom support arrangement. (Personally I don't think it will be any problematic than booting from a kernel on disk, but commercial support models being what they are, that scenario doesn't fall under the supported category yet.) One thing to keep in mind is that putting your kernel into an NSS is only going to save you somewhere around 1-4MB (at most). Unless you have a _lot_ of z/VM guests, that isn't going to buy you much. You're much better off concentrating on implementing CMM (phase 1), or xip2fs. You'll get a lot more return for your efforts there.
