i'm curious....in a virtual server system like xen or vmware, how is
disk-caching handled?

e.g. say you have a bunch of virtual machines, each allocated 256MB RAM, but
the physical hardware has, say, 2GB RAM.  is disk cached/buffered individually
by each virtual machine, or by the hypervisor kernel, or by both?
