Should it be off since no domain kernel is using more than > 880? Xen will support all your memory (unless there's a big memory hole, causing some of it to be mapped above 4Gig). Domains only need highmem4g if they're going to individually use more than 880. > Should dom0 have it enabled to manage all the memory? Nope, Xen manages all the memory, so you should be fine. > Should all > the domains have it since they are drawing on a pool larger than 880 MB? Nope. But... *if* you need PAE, then Xen and all domains do need to use PAE. > Is the answer the same for Xen 3.0? Thanks - John Yes. (and PAE is Xen 3 only). Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals! Mark: To answer a question with a question: What use is a skateboard? Dave: Skateboards have wheels. Mark: My wheel has a wheel! _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
