SECOND VM NOT WORKING

hi, i cant open the second vm, always get the same error
qemu-system-x86_64: warning: Spice: reds.c:2714:reds_init_socket: binding socket to 127.0.0.1:5900 failed
qemu-system-x86_64: warning: Spice: reds.c:3571:do_spice_init: Failed to open SPICE sockets
the yaml files have diferent name for vm and diferent port but not working.

Is Arch supported?

How is Intel DG1 supported?

Recently I got a DG1 graphics card which is the same model as this level1techs post. The post seems written by @arthurrasmusson claiming that DG1 is supported. I'm using this card on a Proxmox host, however the install-libvfio.sh script is not happy with it. The script tries to uninstall proxmox-ve and other Proxmox packages when installing its own dependencies, so unfortunately I'm not able to try this fantastic project.

According to an Intel community post and an Intel graphics virtulization support page, DG1 might have SR-IOV supoort, but lspci -v command didn't list the corresponding PCIe capability, and for the lspci -xxxx output, the extended PCIe capabilities part didn't seem to comply with it's hardware specifications (either Iris Xe or Iris Xe Max, Volume 2c: Command Reference: Registers). It makes me pretty confused.

So the question is, how does this project support DG1? Is it through SR-IOV & VF passthrough or mdev & GVT-g?

Edit: Add lspci -v output:

PVE support?

Hi, I found this awesome project when looking around for a cheap gpu virtualization setup. It looks pretty promising and I am planning maybe give it a try later.

Currently the wiki uses Ubuntu as an example. It would be nice if we can use PVE as host, because I don't want to affect other vms if I did something stupid that crashed Ubuntu. Is there any plan for this on the roadmap?

openmdev.io appears to be down

/dev/shm/* device not created?

This is a fresh ubuntu 20.04 install that I've decided to install to try libvfio. I followed the instructions exactly but after executing arcd start /path/to/your/yaml/file.yaml --preinstall --save in section 5.3.2, I get an error about a non-existent /dev/shm device.

Here is the error:

Semi-relevant side-note: while this is a fresh install, I tried libvfio earlier on a non-fresh ubuntu install and I did get past this step. That is, the /dev/shm device did exist. However, after section 5.3.3 (i.e. I completed all the steps), the looking glass client would refuse to launch, so I figured I would do a second attempt with a fresh ubuntu install.

install-libvfio.sh hangs while at choosenim step

Installer hangs at this step. I've tried installing choosenim separately after the fact to see if it was an issue specifically with the scripts in this repo, and it still failed.

So it sounds like choosenim is a tad broken, but I've been asked to open an issue so we can explore alternatives. Choosenim doesn't seem to have much activity on their repo so I'm unsure if this an issue that will get solved quickly on their end.

Running Ubuntu 20.04 fresh install with just Steam, Discord, and Chromium loaded.

https://docs.linux-gvm.org/ is not working

In the readme it links to https://docs.linux-gvm.org/

This link is broken

Add support for systemd-boot

Right now the script to install libvf.io doesn't support distos that use systemd-boot (like Pop!_OS).
Would it be possibile to add support for it?

Nvidia installer failed

Getting through the libvf.io install.sh script, but it is now failing at the nvidia driver build process on the NVIDIA-Linux-x86_64-460.73.01-grid-vgpu-kvm-v5-custom.run file.. Attached is the nvidia-installer log.

I am running Ubuntu 21.10 with kernel 5.13.0-20 and GPU: NVIDIA GeForce RTX 2080 SUPER Mobile / Max-Q

I also tried downgrading same issue is happening on kernels 5.12.0, 5.12.10, 5.12.19.

Note that I had to purge all the existing nvidia proprietary drivers that Ubuntu comes with, and also got the error in the nvidia run tool that X was running so I had to reboot into recovery mode to get to a text command line before I could get further in the nvidia run tool. Still getting unknown symbol errors though.

Ideas?

Hello there, firstly thank you for making this utility, however there is a slight problem when I tried to start the VM with NVIDIA vgpu (mx230 muxless GPU) it failed with status 0x0 with Input/Output Error. I can't seem to figure it out what is the cause of this issues, is this a hardware issues that can't be mediated or there's some things that i missed?

note: all the hardware specs(lshw), dmesg and run failure log, install log are written in the files below
failedRunLog.log
lshw.txt

How to copy files between host and guest?

Hi,

How can I copy files to and from the guest OS? I've tried copy paste, but that doesn't work.

I see shareddir in the yaml file, but I don't see any mention of it in the docs. I tried using "shareddir: ~/vm_shared" (the folder vm_shared does exist in my home folder by the way, I created it just for that purpose), but the VM refused to start when I did that.

How do I configure a shared directory?

Are there any other ways of sharing files between the guest and host? I saw something here, but not sure how to apply that to arcd.

Usage with Fedora?

Is there any way to use this with Fedora 3435?

Is there a way to use this under Kubernetes?

Hi ArcCompute team,

Is there a way to use this VGpu solution under kubernetes?

By Kubernetes specially I mean Kubevirt.io

Bests,

Proxmox Support

I'm sure this has been requested in the past but is there any chance for proxmox support/ integration, with this project since what is provides is nothing short of phenomenal, i would be extremely helpful it would some how be able to work in conjunction with spice protocol to give that hardware acceleration in proxmox as well as vms.

Achieving an overall smoother experience.

I'm asking this since I see no way of being able to install or configure it in proxmox itself.

Thank you in advanced.

Question: LibVF.IO with existing windows

Is it possible to use LibVF.IO with looking glass to boot an already existing Windows install? I already have a windows system set up in a partition. I was just wondering if I could change the yaml file or pass in some special arguments to make looking glass open my preexisting windows install with the single GPU virtualized in both.

Thanks

Installing patched drivers fails on Fedora 37

Docs re: remote introspection with parsec/etc.

This would be a nice addition to the docs, as I would bet many people looking to partition a GPU would also be looking to run a headless host with multiple clients each accessing a VM with a vGPU. Would parsec work as normal out of the box (I am personally unsure how vGPU interacts with nvenc, for example)? Any particular issues to address in setup?

Is Debian Supported?

Is Debian 11 (Bullseye) supported? If so, should we use "Ubuntu" or "Other" when installing?

I have some error in install script

From what I've been reading with regards to Genshin Impact specifically in a VM they do a simple VM check that is normally defeated by libvrt's feature policy='disable' name='hypervisor' setting. I am unsure how to validate that that is being done when calling Qemu directly like arcd is and I would have assumed this would be covered in the general hypervisor detection preventions as was mentioned by @arthurrasmusson on the r/homelab subreddit.

Unsure if this last bit is worth mentioning, but as this is something of a test for me (Genshin is the last hold-out keeping me on Windows), I am running Ubuntu off of a USB3.1 SSD. Getting some pretty harsh disk access issues but for the purpose of the test that's fine (provided the game actually launches).

looking glass B6 support

Hi, from what I saw in funcs-libvfio.sh, is downloading B4. As you know better than me, B6 is a major update for sound support, and performance, and no need to install IOMMU on the guest.
Would be great to see an update and updated documentation.

BTW: as a total noob I could not use LibVF.io, as for GVT-g the docu just refers to the intel-developer side.....bummer.
After several hours of try and error, I could get it running (with helper scrips from pavolelsig); and then I decided to write a noob tutorial for looking-glass: reddit. IMHO such step-by-step documentation is for an average user simply necessary - not to be misunderstood, LibVF.io is a great project!

`arcd create` works but not `arcd start`

Hi, I followed the new guide for Fedora.

After fixing #24 by @rogerskeie I was able to run arcd create with the default Nvidia file, create the VM, and install windows. The VM launched automatically.

However after quitting the VM as per the guide, arcd start <my_yaml> does not work; I get

I'm confused because the IOMMU group 86 is not the one my Nvidia graphics are on.

`README.md` links to openmdev.io which does not exist.

The README.md links for usage information to openmdev.io, but that domain does (no longer) exist.

Can you link to up to date documentation?

Regards!

Is DisplayStreamCompression (DSC) supported?

In order to use higher resolutions and frame rates like 8k60 or 4k120, DSC must be enabled in the driver so that the link between the GPU and the monitor will compress the signal.

When you boot into Windows native, or use GPU passthrough, DSC is enabled and you can output 8k@60 Hz.

If you boot into linux with the nvidia driver, or use GPU passthrough, DSC is disabled, and you are limited to 8k@30Hz.

Does the use of Libvf.io allow DSC to work?

Alsa error after running "arcd create" command

Kubuntu 21.10, whenever I use the "arcd create" command I get this error:

Everything works fine if I disable audio by adding QEMU_AUDIO_DRV=none in /etc/environment

Typo in virtio-win filename

Should be virtio-win10-prewhql-0.1-161.zip, not vir0tio-win10-prewhql-0.1-161.zip

https://github.com/Arc-Compute/libvf.io/blob/6aa50ade6aa6c620b7a0b1fe93870f87243653dc/scripts/funcs-libvfio.sh#L278

Is vgpu_unlock used ?

Hey i was curious if this tool relies on vgpu_unlock or is its own thing entirely ?
if so how is it different internally ?

thank you very much for the clarifications !

Fedora - Build failed for the package: libvfio (for arcd)

Hello,
When I use ./scripts/install-libvfio.sh script on my Fedora machine with Nvidia GPU, I get the following error during execution:

     Info:  Nimble data file "/home/mble/.nimble/nimbledata2.json" has been loaded.
   Warning: Package 'libvfio' has an incorrect structure. The top level of the package source directory should contain at most one module, named 'libvfio.nim', but a file named 'arcd.nim' was found. This will be an error in the future.
      Hint: If this is the primary source file in the package, rename it to 'libvfio.nim'. If it's a source file required by the main module, or if it is one of several modules exposed by 'libvfio', then move it into a 'libvfio/' subdirectory. If it's a test file or otherwise not required to build the the package 'libvfio.nim', prevent its installation by adding `skipFiles = @["arcd.nim"]` to the .nimble file. See https://github.com/nim-lang/nimble#libraries for more info.

Issues following guide - can't start VM

Hi, I'm testing this out (love the project!) and I'm having issues following the guide's steps after installation.

I can create my initial VM using arcd create /home/bozz/libvfio/vm/nvidia-mdev.yaml /home/bozz/libvfio/iso/Win10_21H1_English_x64.iso 400. After Windows is installed, I shut down the VM (I've tried both shutting it down directly from inside and via arcd stop $UUID). Then I run arcd start /home/bozz/libvfio/vm/nvidia-mdev.yaml --preinstall --save, but nothing happens.

bozz@Snek:~/libvfio$ arcd ps

I poked around ~/.local/libvf.io/ and noticed the following:

The kernel file for 2b698a0b-e72a-46b0-be17-3c96ae01e6fa is in ./live/, though I'd assume it would be in ./kernel/ after stopping the VM.
There's not much going on in the logs... the QEMU logs were empty and the ARCD logs didn't have useful information.
The lock file for the apparently failed VMs are still there even though the VM didn't run.
I checked on mdevctl and I noticed each new execution defined a new device instead of re-using the one from the base implementation. I assume that's not correct, since mdevctl seems to only be able to allocate one device.
Running the QEMU command directly failed with a no such file or directory for the new VM's live kernel file.

Looks to me like copying the kernel files is not quite working, but I don't want to jump to conclusions since I'm not very familiar with the project.

I was able to get the --preinstall --save step to work by grabbing the QEMU command from the console and replacing the UUIDs with the original VM and the vGPU, but it doesn't seem right, since it seems the idea would be to copy the kernel (which seems it's not happening) and re-create a vGPU (which might also not be working, since the original one wasn't destroyed and mdevctl reports 0 available GPUs of any type).

I'm still wrapping my head around QEMU, MDEV and your code so I'm not sure what to look for here, so I'd really appreciate the help. I'm more than happy to provide you with more details and try stuff as well.

BTW, any way I can enable additional logging/debugging on arcd? I didn't see an option for it while looking around in the code.

3070 Ti available on developer branch?

I have a 3070 Ti (Nvidia) on my pc and I want to set up LibVF.IO for a collage project but I know it's not supported, YET. I see that they are in development for making 30** work but I don't know if that means I can download the devel branch and it would "work". Is that technically what I can do or do I have to wait (because I need to get it working for the school protect but I only have so much money left in my funding for my capstone)?

EDIT: I would like to add I'm using fedora 37

initial arcd deploy failing due to missing introspection-installations.rom

https://github.com/Arc-Compute/libvf.io/blob/a3cacab9115e4458ddb895c55bf3232122179a5a/scripts/install.sh#L66

This line is failing because introspection-installations.rom has not been created yet. I ran the arcd deloy line after line 97 creates the rom, and it seems to work fine.

Missing documentation

https://github.com/Arc-Compute/LibVF.IO/blob/master/src/libvfio/types/environment.nim#L72

Why is this function a procedure and not a function, where are the side effects?

Nvidia CUDA support?

Is Cuda supported in a Windows Guest?

minor script detail

sudo su root -c "echo 'f /dev/shm/kvmfr-* 0660 user kvm -' >> /etc/tmpfiles.d/10-looking-glass.conf"

This part of the script is incorrect, the term user is meant to be replaced by the actual user name. Checked this from arch wiki from which I presume this function is inspired from. Maybe add a script to query the user name and add this to the command before running.

Questions about intel SRV-IO / intel XE graphics

Hello,

I'm really interested in LibVF.IO. I have read all the documentation, and before i dive in, i have a few questions if you don't mind.

I'm running Debian Bookworm on a nuc 12th gen, with a 12t gen alder lake iris XE igpu.
this GPU is listed on https://open-iov.org/index.php/GPU_Support as being supported by LibVF.IO

when i read further in the docs i stumble upon this part:

Intel i915 Driver

Instructions on the installation of Intel's bleeding edge virtualization drivers can be found here for use with 6th to 9th generation silicon (GVT-g).

SR-IOV APIs on 11th & 12th generation Intel Xe graphics has not yet been documented in the i915 driver API making support more difficult. Source code for i915 SR-IOV is available here. If you would like to engage with Intel's GPU driver developers you can join the Intel-GFX mailing list here.

This makes me doubt. Is there anything i should take into consideration using LibVF.IO with a 12th gen iris XE?
or, would this mean that it's partially supported or something? :)

Also,

at this moment, i'm using gpu passthrough to docker containers for hardware transcoding.
for that, i passthrough /dev/dri:/dev/dri to a few containers.

Will this still work, would i be using LibVF.IO ? or do i lose this ability?

and one last question:

do i get 'real' virtual graphical cards?
Do i need to provide 'hacks' inside the guest VM's in order to make this operate?
i see i need to install a vm with arcd /path/to/yaml/ path/to/iso 100

can't i just pass a GPU through to a KVM VM ? or would that not work ?

Debian bookwrom support

Tried following setup guide on clean installation of Debian 12 Bookworm RC 1 and did not go as planned. I manage to start VM but display driver seams to not work.

First think I needed to change was to remove qemu package from apt install cause its no longer available in newer sources but since its dummy package I do not think it causes any problems (but its needs to be done other wise installation of other packages also fails)

Then first step went as expected after restart got small res screen. Starting again got prompts as mentioned in guide (plus telemetry prompt from choosonim) but after restarting display was still in small res (and could not be changed). Creating vm works but do not shows nvidia graphic device in windows Device Manager.

Are there any additional requirements from host to make it work?
If you think it can help I can re run those steps to get full logs from installation.

Hardware:
Intel i9-9900K
Nvidia Gefroce RTX 2080

So I'm receiving this error, i'm using the archinstaller

Creating a new VM Fails - Ubuntu 20.04.3

Hi. I'm trying to install install a Windows 10 VM using libvf.io and I'm following the instructions from here. This is the inxi output of the machine . I was successfully able to complete till Step 5.2, but when I try to create a new VM as in 5.3.1 with the arcd create command, it does nothing.

Here is what I see in the ~/.local/libvf.io/logs/arcd logs.

Can't get LibVF to pick up after reboot

I'm using fedora 37 and when I install LibVF I reboot and then the script does NOT pickup where I left off. It starts the process all over again. I have no clue what I'm doing wrong and I've tried fixing it for days. Can anyone help? I'm puting a pastbin of the output below.

Any help is nice so thank you in advance.

Include summary about what is supported and how well right from the README.

One of the first questions people will wonder is if it will work with their hardware/software configuration.

Having been bitten by AMD promising GPU IOV being widely supported, i'd probably rate the current support for that as "sad" or very sad !

At the moment this whole thing is a bit of a dark art, and next time I choose HW, I'd like it to be some that works with LibVF.IO, it would be great if I could easily get right from the project page to a place showing current support.

(And once this all kicks off, there is the very very dim hope we can shame AMD into some action themselves).

Docs re: migration of existing VMs

Would be a nice addition, as I presume many users have existing VMs they would like to integrate.

What API does it support in windows Virtual machine?

just take GPU-Z for example
if I passthrough RTX 2060 to a windows virtual machine
gpu-z will show that it supports

all the features are available

if I use LibVF.IO
will the features all be supported in windows VM ?
many games need direcx12, pytorch need CUDA, and some other applications need OpenCL, OpenGL and so on.
I have used Vmware Workstation in linux, and the windows guest only supports direcx11, other API support is also very bad.
(I will not pay even a cent to Nvidia grid license

Add spice guest tools to the preinstall [Feature Request]

Without the guest tools installed looking glass does not allow for copying/pasting to/from the host, it would be helpful to have that working from the get-go.
