Some applications, like Oracle Directory Server, use cached memory and never release it. Users need to take this memory into account when planning the memory requirements. Please report guests Buffered/Cached memory in addition to used memory, currently reported as a percent bar. I'd suggest to add a field in Guest General sub-tab with "Free: X, Buffered: Y, Cached: Z."
added way after 3.5 dates. moving out, please bring up for future release planning sessions
