WHY IS IT SO HARD TO DUMP A VBIOS

#server #gpu #vfio #proxmox

So my HP Prolaint ML350 Gen 9 has a intigrated matrox gpu in the motherboard but apparently still would rather piggyback of whatever gpu is installed by shadowing its vbios so now i have isssues with my intel arc a310. Good job HP

We have a Windows 10 VM laying around that we use to configure our mouse (and currently nothing else).

I wonder if we could do GPU passthrough and play VR games on it...

• How much is it possible to strip Windows of its adshit and its trackingshit? Obviously it's still not going to be anywhere near as trustworthy as Linux, but like, still. If we're going online with it at all and playing games on it at all, I want it to be not shipping everything we do off to Microsoft QUITE so much.
• Is single GPU passthrough feasible? Is it annoying? Is it worth the hassle? We actually have an RX 580 laying around that we could shove into our desktop, but our RX 6600's fat butt blocks the only other PCIe slot on the motherboard, IIRC, and also I still want to use the RX 6600 for Linux games (and Blender renders and stuff) when we aren't using the Windows VM.
• Is there a good way to add a second GPU when the first GPU's big fat butt blocks your PCIe slots? Would we just have to buy a new motherboard? The case is plenty big enough to support it, we just have a microATX motherboard because it was the cheapest at the time.
• Or should we just ignore Windows and try to get Linux VR working through the open source tooling, without SteamVR, and somehow able to play Steam games through it? The major issue with SteamVR is reprojection double vision making us want to puke.

Just realised I haven’t touched the VFIO with looking glass setup that I spent days to get it work for months… damn

#linux #vfio #lookingglass

yesterday, i booted into the VFIO specialization for the first time since i reinstalled NixOS. i opened OBS and, as i kinda expected, it didn't work; i couldn't record the screen or capture windows. today, i booted into normal NixOS, where the GPU isn't restricted to virtual machines. and uh. yeah. OBS stopped working again

so i have a theory:

somehow, the NixOS specialization for VFIO is interfering in some way with files or configs or bindings or whatever, that are persistent, even after i turn off my laptop and boot into normal NixOS. this is the only logical explanation i can come up with. i'm using the exact same config i was using before reinstalling, when it was broken, and it was working, and then it stopped working

TLDR there's something that persists after the first boot into VFIO mode, that's preventing things from working normally in some way

#NixOS #linux #VFIO #OBS help me. i do not know what to do. here's my NixOS virtualization config file ​:boosts_ok_gay:​

Мой идеальный компьютер

Я сижу под Linux, но иногда нужна винда. До недавнего времени у меня был обычный dual boot, но сейчас я реализовал свой идеальный сетап: - основная система - Linux - Windows - на выделенной SSD - на нее можно загрузиться как из груба, так и из виртуалки - с пробросом второго GPU (дисплей на отдельный физический выход) - с качественным удаленным подключением (как RDP, но быстрое) - можно играть в игры Ниже опишу что и как сделал.

Sometimes I feel really stupid that I just went to set the screen to 4k for my Windows virtual machine while the GPU I passed through is 2060 Super...

#vfio

yk what i'll just tell you what's wrong

even when i select the "no passthrough please" option, when the systemd output is on screen it ocasionally says something along the lines of "the gpu is already bound to vfio" which leads me to believe that the boot option is not working bc it's not letting the host use what i'm passing through to it. oddly enough i can't use virt-manager when i'm not in passthrough mode

yea i need help pls help me ​:BlobCat_BigSob:​ #nixos #nix #vfio #virtualmachine #virtualmachines my current virtualisation config is at github.com/JuxGD/nixconfig/blob/94d149a7d81fbd48735a091a7d0fa470318d79a6/virtualisation.nix

when you accidentally started krfb that the libvirt vm spice server moved to port 5901 automatically and then I am there trying to figure out why looking glass keeps crashing ​:neocat_googly_woozy_shocked_explode:​

For my fellow penguin's wanting to get into #vfio and #gaming on a #windows #virtualmachine you are in luck, i am sharing my configurations for this so you can use them in conjunction with a guide
https://git.xaetacore.net/jeroenmathon/vfio-configs

Feel free to copy it, please read the README it has some important pointers and tips on how to incorporate this into your own setup.

Please let me know if you need feedback and if you want to contribute let me know :)

Time to tune my windows VM so i can play some games better ,i was thinking of CPU Core Pinning and More RAM.

#vfio #virtualization #kvm #linux #windows

Finally get the Windows VM back…

everything about upgrading Fedora went smooth except everything went wrong

Why you ruined my /boot partition, overwrite my kernel parameters, and decided I should use GRUB instead

Fedora why you like this

Nothing to see here, it's just Minecraft Bedrock Ray Tracing on GPU-passedthrough Windows virtual machine

Finally, after so many days of researching and investigating, GPU passthrough with looking glass is finally done

This is so much better than dual-booting.

- Windows 11 running in KVM
- Dedicated 2nd graphics card (cheap 1030)
- ParsecVDA virtual display adapter, always on and passing video
- Looking Glass for live-speed video
- Creative Cloud and Lightroom working as though native
- MacOS Catalina in a VM on the side just for fun
- Upgraded to 64GB of RAM to make all this work.

I won't be gaming on it, but it runs Lightroom just fine, which was my last holdout application I couldn't live without.

After a quick check of my backups I can wipe my dual-boot Windows drive completely, finally!

#linux #windows #lookingglass #vfio

My #GenshinImpact under #VFIO #passthrough stopped working yesterday (booting Windows using the same disk works flawlessly).

I suspect they added new checks, and maybe TPM chip is related, but still didn't found the button. Any ideas?

just to explain a lil further why I researched PCIe passthru on Proxmox yet again last night:

after learning that another of my friends is seriously affected by environmental noise, I'm experimenting with masking noise over speakers (not headphones or earbuds). this has been an on-and-off focus of mine since I was in college long ago.

anyway, having forgotten the last 3 times I did this, I hooked a USB audio device up to my music+audio VM and ran into the crackling problems I did before. USB passthru in Proxmox just can't meet the needs of live audio. so I looked further into PCIe passthru to see if there was a way to break up the giant IOMMU groups offered by my highly-integrated mini PC, without using a kernel patch which does so by introducing a giant security hole.

there is something called PCIe Access Control Service (ACS) which can break up the IOMMU groups, but as best I can tell it's not supported by the HP EliteDesk Mini 805 G8 and/or the Ryzen 5750GE APU. this ends my quest for PCIe passthru.

so I'm now using Bluetooth to a speaker 2 feet from the server, because somehow, USB passthru of a *Bluetooth* transceiver in #Proxmox can do audio just fine, whereas passthru of a basic USB DAC cannot. 🙄 #VFIO
