There was a patch worked up by Christoph Lameter that was never accepted into the kernel. http://lwn.net/Articles/218890/

Hi all, One of the problems with Linux under VM (not just z/VM I guess) is that no matter how much memory you allocate to the guest it will consume it all as cache. It just seems reasonable to be able to limit this cache to a user defined value leaving the rest of it for the applications. Sadly I couldn't find a parameter to enforce this limit. So, my question is, is there a way to limit the cache? If not, why? Obviously this caching method is just not good enough under VM. Decreasing and increasing memory for a guest is quite disruptive and adding 100M to an oracle guest just looks bad :-) Thanks! Offer Baruch No virus found in this outgoing message.
