No Dave, locked pages is "material" (i.e. hardware). Unlocked pages are "immaterial" (virtual) :-) In a former live, in the days that I cared about such things, I had a tiny pipeline stage that could read the core table (using my dcp stage). From there it was trivial to select the entries marked as locked user pages. I used it to determine the reference patterns for Linux pages to decide what portions would be candidates to share. But if your "which" was only the prelude for the "why" question: if the guest has a dedicated OSA adapter, then the locked pages are probably the inbound buffers for that. In previous releases the locked pages per guest (under the bar) was part of the motivation to promote virtual network devices. Rob
