Hello, I am trying to build a gaming guest (Ubuntu, Mint, SteamOS or something Ubuntu-LTS-based) on a gentoo host. The host is mostly gentoo amd64, hardened kernel (but with some options disabled to not get in the way), PIC/PIE and SSP toolchain. Relevant versions are:
kernel-4.4.8 libvirt-1.3.4 qemu-2.5.1 The UEFI image is from here, as of 2016-06-24: https://www.kraxel.org/repos/jenkins/edk2/ Two nvidia graphics cards: The passive one (no fan) is a GeForce GTX 750 Ti. Used by the host. The active one - a GeForce GTX 750 - is "hidden" from the host via pci-stub.ids boot parameter and assigned to the guest (both the video and the audio device, which share one IOMMU group, with no ther devices in the group). The card is UEFI capable, according to the test program from here: http://vfio.blogspot.de/2014/08/does-my-graphics-card-rom-support-efi.html I can install Ubuntu 16.04 fine and it works, as long as it uses the nouveau driver. The nvidia driver is listed in "Additional drivers" as compatible and can be installed, but on guest reboot the X server cannot use the card. These dmesg lines from the guest appear relevant: [ 4.948877] NVRM: RmInitAdapter failed! (0x23:0x56:464) [ 4.949354] NVRM: rm_init_adapter failed for device bearing minor number 0 <repeated 12 times> Xorg.0.log says: [ 9.285] (EE) NVIDIA(GPU-0): The NVIDIA GPU at PCI:0:2:0 is not supported by the 361.42 [ 9.285] (EE) NVIDIA(GPU-0): NVIDIA driver. [ 9.285] (EE) NVIDIA(GPU-0): Failed to initialize the NVIDIA graphics device! Full logs are linked below. I am sure driver versions 361.* support GPUs in the 700 range. The host has nearly the same configuration with nvidia-drivers-361.28. When I try to start the guest with "nomodeset" kernel parameter, the host hangs. Not even Alt+PrintScrn+REISUB is possible. CPU is a Core i7 5930K, on a X99A mainboard (MSI X99A Gaming 7). Before I start aimlessly changing things: Does anyone have an idea how to make it work, with nvidia-drivers in the guest? Things I could try: - update kernel - update libvirt - update qemu - guest boot options: acpi=off, noacpi, noapic, nolapic, vmalloc=xM, ...? - switch to non-hardened host kernel - switch to non-hardened host toolchain (will take a while to rebuild everything) - try other distributions as guest - other version of guest nvidia driver - switch the graphics card for the guest - Guest dmesg: https://bpaste.net/show/719a56868947 Guest lsmod -k: https://bpaste.net/show/d9b6dc11bf71 Guest lspci: https://bpaste.net/show/18d489d5f77c Guest Xorg.0.log: https://bpaste.net/show/e19d4bd301a3 Guest configuration: https://bpaste.net/show/b2862886ee84 Host kernel config: https://bpaste.net/show/7536e18f0131 - Many thanks!
