Hello list, With all the discussion on PV on HVM drivers, I was wondering if there was such a thing as HVM on PV. To explain what I mean, is there a facility in Xen to run HVM drivers such as the ACPI system in a paravirt-ops (PV) guest domain? The question arose when I noticed that the Linux driver for my "ATI Technologies Inc RV620 LE [Radeon HD 3450]" card was dependent on particular ACPI functionality such as the ACPI button kernel module. Searches on the internet for Xen and ACPI drivers seems to wind up in a dead end or ends up pointing to the host (dom0) processor ACPI kernel module that is used for xenpm (power management). Thanks. -M
