If I were to define a DCSS as type SN and populate it with a filesystem full of data, how is z/VM going to share it among several Linux guests?
I'm assuming that the pages of the DCSS are shared among the guests such that there's really only one page actually in memory and that every guest is mapped to that page right? So, what about the pages that are written to? I understand that for type SW, every guest would see the updated page and there's still only 1 page in memory. But what happens for type SN? If a guest writes to a page, are the updates visible to the other guests? I know, I know...I can just test it myself, but it would be good to hear it from the ppl that know for sure. Thanks, Leland
