KVM PCI passthrough
Hello!
I've been toying around with PCI passthrough. It seems to work okay somewhat (I can see my device in my VM) but nvidia does not want to play (error 43).
Relevant system parts: CPU: i5 4570 Mainboard: ASRock z97 Extreme6 GPU1: IGP (intel) GPU2: NVIDIA GeForce GTX 650 Ti

/sys/kernel/iommu_groups/26/devices/0000:0b:00.0I used the ACS Override Patch present in the linux-vfio kernel. So far everything seems to be in order.
Then I created a VM in virt-manager, changed the disk to be my Windows drive and added my gpu to it (had to do some tinkering to stop a bluescreen while booting, but that was a disk driver thing)
My GPU shows up in the Device manager, together with the "Standard VGA Graphics Adapter". The nvidia card reports Error 43.

I am not sure what this means. Does this mean, that I cannot do pci passthrough with my current setup?

<nvram template='/usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd'/>
</os>to the VM config, This does give me a UEFI shell inside the VM (my keymap does not apply there), No output on GPU
I have tried removing all video and graphics devices from the VM (except my passthrough device). This results in no GPU output, but the UEFI-shell is a proper shell now (I can scoll/select stuff with my mouse and it uses my keymap)
this is probablx unrelated, but I could not get windows to boot with uefi

Re: KVM PCI passthrough
Try with the qemu command listed just above the "Create and configure VM for OVMF" section.
That will help to detemine whether the problem is with libvirt or the basic configuration.

Re: KVM PCI passthrough
Hello!
Thanks for your reply, I have done that already (sorry for my post being a bit long and not well structured)
This is the result of the command:
I get a QEMU console with an imput prompt that states
compat_monitor0 console
Sadly, I do not get any output on my GPU. (If I ommit the "-vga none \" line, I get a proper boot sequence (bios stuff and such, no actual OS obviously))

Is there any more information that could help?

Comparing that with the output on the wiki suggests vfio-pci may not have been succesfull with taking over the card.
Please post full dmesg.

When using the 'base' hook in the initramfs, all modules specified in the MODULES array are loaded statically early in the boot process. The same behavior can be achieved with the 'systemd' hook by using the 'rd.modules-load' kernel parameter to specify modules that should be statically loaded early.
rd.modules-load=vfio-pci,...
content of /etc/mkinitcpio.conf
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES="piix ide_disk reiserfs"
MODULES="vfio vfio_iommu_type1 vfio_pci vfio_virqfd"
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
FILES=""
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
## This setup specifies all modules in the MODULES setting above.
## No raid, lvm2, or encrypted root is needed.
# HOOKS="base"
#
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS="base udev autodetect block filesystems"
#
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS="base udev block filesystems"
#
## This setup assembles a pata mdadm array with an encrypted root FS.
## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
# HOOKS="base udev block mdadm encrypt filesystems"
#
## This setup loads an lvm2 volume group on a usb device.
# HOOKS="base udev block lvm2 filesystems"
#
## NOTE: If you have /usr on a separate partition, you MUST include the
# usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block lvm2 filesystems keyboard fsck"
# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression

Re: KVM PCI passthrough
I don't see problems in the dmesg, but there's one thing we can check :
post lspci -k , it should clearly show if vfio_pci was sucessfull in isolating the Nivida card from the kernel.
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: KVM PCI passthrough
I'm having similar problems having followed the same guide, although I haven't set up a VM using virt-manager yet. I'm trying to verify that the set-up works with QEMU from the command line, but I get no signal on the discrete GPU and no errors reported.
Motherboard: ASUS Z97 Pro
Processor: i7-4790K
Host GPU: IGP
Guest GPU: NVIDIA GTX 970
VT-d option has been enabled in BIOS, and the host is booting on the integrated graphics. I understand there is some dubiousness related to whether this board actually does support VT-d, but I wanted to test it and make sure, before ordering another one.

Re: KVM PCI passthrough
By using nomodeset kernel option, -nographic and without using OVMF, I managed to get the Windows 10 installation to boot on the NVIDIA GPU. I also note that the VGA output on the IGP locks up at the same time. Do I need to patch my kernel?

Re: KVM PCI passthrough
After reading the vfio-users thread referenced in https://bbs.archlinux.org/viewtopic.php … 1#p1564211, I was able to figure out the proper QEMU command line to get this working on my machine:
qemu-system-x86_64 \
-hda d/windows.img \
-monitor stdio \
-M pc-i440fx-2.1 \
-enable-kvm \
-m 2048 \
-cpu host,kvm=off \
-device vfio-pci,host=01:00.0,multifunction=on \
-device vfio-pci,host=01:00.1 \
-drive if=pflash,format=raw,readonly,file=/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd \
-drive if=pflash,format=raw,file=/tmp/my_vars.fdIn particular, I removed the x-vga=on option, as this should apparently not be used with OVMF. I erroneously believed QEMU would boot on the NVIDIA GPU with OVMF from the get-go (similar to VGA passthrough on Seabios), but in this case the NVIDIA GPU only turns on when Windows has finished booting up and has a driver installed for it.
I also added -M pc-i440fx-2.1, as recommended. Windows 10 doesn't seem to boot without it - just get screen corruption on the QEMU VGA display.
I did not do any kernel patching, as this is not required with OVMF.
So far seems to work great. NVIDIA driver is running, IGP seems to work fine while the VM is running, and can restart, power down the guest without issues. Guess I won't have to buy another motherboard, after all.

Re: KVM PCI passthrough
Hello,
thanks for your input on the matter. Glad to hear that it is working now. I have not given up on the matter, but I still have trouble booting windows with ovmf. I am still stuck with an uefi shell, and cannot figure out a way to boot. The system boots fine without omvf.
This guide mentions that calling this
cp /usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd /tmp/my_vars.fd
qemu-system-x86_64 \
-enable-kvm \
-m 2048 \
-cpu host,kvm=off \
-vga none \
-device vfio-pci,host=02:00.0,multifunction=on \
-device vfio-pci,host=02:00.1 \
-drive if=pflash,format=raw,readonly,file=/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd \
-drive if=pflash,format=raw,file=/tmp/my_vars.fdproduces an uefi shell on the GPU output. Do you know why it does that (and not for me/us)?
Did you need to change anything in order to make win10 boot with ovmf?

Re: KVM PCI passthrough
Yeah, the guide is correct. The behavior I'm seeing is related to not having -vga none. With -vga none set, I do get the UEFI shell on the GPU (although, embarrassingly, on a different monitor from what I expected it to produce output on, so I'm wondering if I may have missed that previously).
I didn't have to do anything to get Win10 to boot off OVMF, but I did install it from scratch using OVMF using the freely available ISO from MS. I'm currently testing it out before deciding to upgrade my native Windows 8.1 install to a virtualized Windows 10 environment. In between all the tinkering, I did also update OVMF to a more recent build from the repository, so am not sure if that made a difference. edk2.git-ovmf-x64-0-20150921.b1222.g8cfd008.noarch.rpm is the one I'm running at the moment.

Re: KVM PCI passthrough
I've tried to set this up too. Although with an R9 290 instead, but I'm unsure what I'm doing wrong here. I've checked various posts out but also the wiki page on PCI passthrough via OVMF. I believe I've at the least successfully isolated the GPU I'm going to give to the VM. The host is using my 6600k's integrated GPU.

You forgot to add
-vga noneto your qemu command line. Without it, it will always start with emulated vga (inside a window).

Alright, now I get a monitor and htop notices some CPU activity.
https://i.imgur.com/dRKBXkI.png
I'm still not getting any output from my GPU. Neither through DVI nor HDMI. Yet I'm not getting any error messages from qemu; so I'm unsure whether or not it grabs the card or not. Qemu doesn't happen to log what devices it grabs somewhere?
It might be of help mentioning that I've been unable to get any valid output on my second screen since I isolated the GPU in combination with that I selected the CPU as the primary video output. If I plug my primary monitor out and connect the other to the motherboard via DVI (to my motherboard) I get static noise on half of the screen. I'm also unable to see the motherboard's splash screen with that monitor (plugged into the GPU). This might be an issue with my motherboard settings. I'm using an ASUS Z170-A with the latest BIOS.

Ah sorry. I'll keep that in mind.
I've looked around a bit more, and figured that I have no need for libvirt currently. I'll focus on getting any GPU output first and foremost. My qemu script is the same, except for the added -vga none parameter. I still get no output on the GPU. However, when I enter "info pci" in the qemu monitor a VGA controller and an audio controller are listed, both having the same PCI device ID as on the host. I believe dmesg says the same, given the ouput:

It might be that I'm unable to get any GPU output with OVMF at all, alike you tryllert.

I believe this will be something I'll have to try as well. Although, I don't believe I'll need the nomodeset option, as I don't get any errors from qemu at the current. But do you use a special version of the Windows ISO or could any of them be used? I can also see a "windows.img" in your script, am I right at that being the container or is it something else?
tryllert wrote:

Maybe it's a dumb question, but how did you manage to install the necessary drivers if you couldn't get any video output? :s
EDIT:
Some progress, maybe. Downloaded a Windows ISO from here and changed my script to the following:
#!/bin/bash
cp /usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd /tmp/my_vars.fd
qemu-system-x86_64 \
-enable-kvm \
-m 2G \
-hda /home/tmplt/qemu/windows.img \

-cdrom /home/tmplt/Downloads/Win10_English_x64.iso \

-device vfio-pci,host=01:00.1 \
-drive if=pflash,format=raw,readonly,file=/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd \
-drive if=pflash,format=raw,file=/tmp/my_vars.fdWhile I'm able to boot onto the Windows ISO (alas not getting a graphical interface, I can only pass the "Loading Files" part), it appears as a new window on the host rather than outputting through the GPU even though the -vga none parameter is in use. I've looked over everything that should be in place (which they seem to be), but I'm still not getting a GPU output. Any ideas?
Edit
Another user has reported a successful attempt on an older AMD card after it was flashed with a UEFI BIOS. The reference R9 290 does not have that, but according to this thread a BIOS from another vendor can be used. Once I have time, I will flash my card and try again.
2016 Edit (hopefully I'm not grave digging, here)
I have now flashed my GPU with what I have linked with this post.
With the following command, I get video output from my GPU passed to qemu:
sudo qemu-system-x86_64 \
-enable-kvm \
-m 2048 \
-cpu host,kvm=off \
-vga none \
