The original idea was that PVH should be as close to PV as possible; this was back when we were still hoping to have a "lightweight container" rather than the full HVM stack. Since "lightweight" isn't actually that lightweight, we're sort of moving towards "PVH is HVM without a device model". -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
