Hello everyone! What would be the steps for installing and trying out different Xen versions in Qubes 3.1? Or even switching to KVM? Shouldn't HAL make this possible on Qubes 3.0+ ?
I'm mainly interested in testing Xen 4.3 branch, since there's anecdotal evidence that something might have broken with GPU passthrough between Xen versions 4.4 and 4.3 and I have not seen any success stories of passthrough after 4.3. http://www.gossamer-threads.com/lists/xen/users/349649 https://lime-technology.com/forum/index.php?topic=36101.0 https://www.linuxserver.io/index.php/2013/09/12/xen-4-3-windows-8-with-vga-passthrough-on-arch-linux/ Only exception is here: https://groups.google.com/forum/#!topic/qubes-users/cmPRMOkxkdA with Qubes 3.0RC2 but he seems to be using AMD GPU & CPU whereas I'm with Intel and Nvidia. Personally I've been trying to get the GPU passthrough (as secondary GPU) working for the past two weeks now, without luck. It's always the same result: Windows BSODs during the first boot after driver installation. I've tried Windows 7 Pro SP1 and Windows 8.1 and both act the same way. I know it's not a hardware problem, since GPU passthrough using *KVM on Arch Linux* *works without hiccup*. Also the same BSOD happens with Xen on Arch Linux, so I also know that *it's not restricted to just Qubes. *Also it's not about the well-known problem of "BSOD after 2nd boot", since with KVM I could boot DomU many times flawlessly without any requirement to boot Dom0 (to reset the GPU as well). I've tried out these OS's with stock Xen versions: Arch Linux, Xen 4.6.1: BSOD on DomU boot Qubes 3.1, Xen 4.6.0: BSOD on DomU boot Qubes 3.0 RC 2, Xen 4.4.2: BSOD on DomU boot Qubes 2.0, Xen 4.1.6: Sadly BSOD on DomU boot here as well.. My current HW is: Intel I7-5820K Asrock X99 WS EVGA GTX 980 (passthrough GPU) Asus Radeon R5 230 (dom0 GPU) I've tried also Radeon as passthrough GPU on Xen 4.6.0 with many driver versions (win 7 pro), but with same results. I would be very interested hearing what kind of results others have achieved! -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
