Filesystem caching shouldn't happen in dom0 for the domU's and I doubt you'd 
it to.  Caching *will* happen at the domU level and that's where you want it --
close to your applications.

Besides, if you can run a dom0 in like 128MB of memory to devote as much as
possible to your domU's, how much caching could you do?
