In the end, after installing ovmf, i followed this tutorial on how to set it up using virt-manager and ovmf:
QEMU VGA SETTINGS INSTALL
apt-get install ovmfĢ- The windows nvidia drivers were detecting that i was running windows on kvm and where blocking my gpu.

QEMU VGA SETTINGS PATCH
My only option left is to try downgrading my kernel from 4.2.0-27-lowlatency to 4.1.x, and i'm worried it will screw up my OS.Īfter much researching, i noticed 2 main problems:ġ- There was a problem with my integrated graphics card i915 drivers, and i found out that i either had to patch my kernel with an unnofficial patch, or install my virtual machine on UEFI mode, and simulate a bios startup. vfio_ecap_init: 0000:01:00.0 hiding ecap 130.988196] vfio_ecap_init: 0000:01:00.0 hiding ecap after all this, the monitor still doesn't get any signal. I can bind the gpu to vfio-pci drivers easily and without crashes, and the output after launching kvm looks like this: vfio-pci 0000:01:00.0: enabling device (0000 -> 0003) I just downgraded to Ubuntu Studio 14.04, and i finally was able to make pci-stub grab the gpu before the nvidia/nouveau drivers.
QEMU VGA SETTINGS DRIVER
If i remove the "x-vga=on" parameter it still works fine.Īfter some further testing and researching on this issue, i discovered that tha vfio-pci driver wasn't enabling the gpu when i launch kvm.Īfter starting kvm, "dmesg|grep -i vfio" command returns these new lines: vfio_ecap_init: 0000:01:00.0 hiding ecap 1572.975063] vfio_ecap_init: 0000:01:00.0 hiding ecap should be another line similar to this one : vfio-pci 0000:01:00.0: enabling device (0000 -> 0003) This is because of the line: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,x-vga=on \ If i do this, the vm seems to run without major problems, but when i don't, the qemu monitor freezes when i try to start it, and i can't close it or stop the process unless i "kill -9" it. Usually, before i try to launch the vm, and after i remove the nvidia modules, i remove the device and rescan it: echo > 1 /sys/bus/pci/devices/0000:01:00.0/removeĮcho > 1 /sys/bus/pci/devices/0000:01:00.1/remove I really appreciate any help you can provide. I need some help to figure out how to solve this, or at least find a viable alternative to this method.Īs additional info, i'm using Ubuntu Studio 16.04, my first monitor is a Samsung monitor plugged to the Intel DVI-I port, and my second monitor is a BENQ with one VGA and one DVI-I port, and i have it plugged to the GTX 960 DVI-I port (this model doesn't have VGA port) The monitor doesn't seem to receive any signal. drive file=/home/xanty/Descargas/windows7pro.iso,id=isocd,cache=none,if=none -device scsi-cd,drive=isocd \Īnd i finally got it to run, and when checking the pci info on the qemu monitor (pic here), everything looks fine, but the second monitor i have attached to my nvidia card's DVI-I port doesn't show anything. drive file=/home/xanty/windows1.img,id=disk,format=raw,cache=none,if=none -device scsi-hd,drive=disk \ bios /usr/share/seabios/bios.bin -vga none \ Sudo qemu-system-x86_64 -enable-kvm -M q35 -m 4096 -cpu host,kvm=off \ I checked that this worked by removing the device(gpu), and verifying that the card was being claimed by vfio-pci instead of nvidia drivers when i rescanned.Īfter i had all the drivers set up, i started the VM with this script: #!/bin/bash I tried to blacklist the nvidia drivers and use pci-stub to "steal" the GPU from them, so i could avoid any possible errors, but it didn't work, so i manually unload the nvidia modules after the OS starts, using this script(in console mode): #!/bin/bash I installed the NVIDIA drivers, and i managed to bind the nvidia card to the vfio-pci controller without any problem, after disabling hybrid graphics in the nvidia settings.

QEMU VGA SETTINGS PC
My pc uses an intel i7-4790 with an integrated intel HD 4600, which i use as my primary card, and an NVIDIA GTX 960 which is the one i want to pass throug. I have tried all types of mouse: PS/2, touchpad and USB.These last few days I've been trying to set up a windows virtual machine with VGA passthrough, using this guide as my main reference:

In QEMU, only one a is written at start, and only when I release the key, all others are written at once. Normally I would expect a's to be typed every x miliseconds. So let's say I press 'a' for several seconds. Second: keyboard doesn't handle holding keys well. That means every time I move, first I see host mouse moving and then guest mouse slowly gets under it. I'm running Windows 8 in QEMU KVM, and two things make it not very usable.įirst: mouse is slow (it lags behind movement) and I see the most mouse.
