Great video well done

This was a lot of fun to watch, TheMaster. A note for all of you: If you need a CPU-instense / graphics intense machine for, for example new games such as at the date of writing this in April 2021: Cybpunk 2077, VR games with your VR headset on PC and last but not least city simulators which eat CPU such as: Simcity 2013 and City Skylines, both my favorite city games, its best to go with the real stationary machine. (Don't do laptop for gaming).

Hi all, hopefully you find the guide helpful! I have recently done a follow-up to this video where I go over some things from the video: kzread.info/dash/bejne/dZ5spKVrgJDWcrA.html I also came across an Arch Linux guide covering this stuff so I will link it here: wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF Plus I did another follow-up video where I go over the problem at the end of the guide where Windows would know it's a virtual machine when we don't want it to say that: kzread.info/dash/bejne/lohnksaRqta2hZc.html If you have any questions/corrections, read through the comments/responses in this video and check out the two follow-up videos then let me know and I will see what I can do. Take care!

Great video do you think it would be better to use fedora as it has the latest virt manager release

I would say it doesn't matter too much, I did this on Ubuntu and it works fine so if you choose to use Fedora/Debian or something else, that's fine.

Thank you for the interesting video, the concept was tottaly new for me, therefore I'm very curious if the whole process gives you any sort of tangible performance boost in terms of GPU rather than the one which you're actually using?

@TheMaster974

Thanks for the comment! I don't think this process would lead to any different GPU performance, since the virtual machine has full access to the dedicated GPU so it would be the same as using a native install of Windows 10. However, I would expect slightly lower CPU performance, since the processor needs to support the virtual machine and the hypervisor.

can you use 2 dedicated gpu's? as i don't have onborad gpu on my MB

@TheMaster974

I think you should be able to, as long as the dedicated gpu you want to use is plugged into your pc and is in its own separate iommu group (you can determine this by following the steps presented in the video up to around the 20 minute mark, as this goes over the overall setup and initial Linux steps to get the virtual machine working as intended). So one dedicated gpu outputs to the Linux distro you want to use (i.e. Ubuntu) and the other outputs the virtual machine feed. Hopefully this is helpful!

Yes you would, also make sure that the display output setting in the BIOS is set to the option that is not PCI to ensure that the installation of the host OS/usage of the host OS displays to the monitor that is connected to the motherboard, as you don't want to use the dedicated GPU in your host OS at all (you want to pass through 100% of the dedicated graphics to the virtual machine).

Does it matter if there is just two devices in the iommu [20:09] edit: I have a brand new Ubuntu install, what about PCIe Link? edit: my linuxOS is completly black

@TheMaster974

3 жыл бұрын

Firstly, I have absolutely no idea if PCIe Link affects anything about this procedure! Anyway, to answer your question, it depends on what two things are there. If it's, for example, showing something like 01:00.0 and 01:00.1, then this is the graphics output and the sound controller for your graphics card, which is good, meaning you can continue with the guide. If it says something like 00:01.0 and 01:00.0, then this is the PCI link and the graphics output for your graphics card, which is bad, as this means you will not be able to hear audio in the VM as the audio controller hasn't been passed through. If it's the first case, then the PCI Link not showing isn't really important as it's the other ID's that matter (as these are needed to obtain the relevant hardware ID numbers that means you can pass the graphics card through to the VM). Otherwise, if it's the latter case, you may not be in a position to continue. Hopefully this helps!

I couldn't find the the onboard graphics change on my tuf gaming x570-plus

@TheMaster974

The internal/onboard graphics is purely on the processor not the motherboard, so there may be the possibility that your processor has no internal graphics hence why no option is present. It might be worth searching the processor model online and seeing if it has onboard graphics or not. If the processor you have has an internal graphics card, enable advanced mode in the BIOS (F7 from screenshots, from what I've seen) and browse through the different tabs until you find the right option. Otherwise, you can't really follow this guide since this is a must have requirement to progress. I don't have this type of motherboard so I can't really tell you where to go. I hope this helps!

can I use 2 amd graphics cards? for example a r7 250 and and a 5700xt

@TheMaster974

4 жыл бұрын

I think you can, you have to follow the guide in a similar fashion as I show and make sure you can isolate one of the dedicated graphics cards (iommu group stuff at around 19:40 is important), just look out for the fact the amd drivers may try and take a hold of the graphics card you want to isolate, which may introduce difficulties with later steps. That's all I can really say, as I cannot try this myself (I don't have 2 dedicated graphics cards). Hopefully this is helpful!

4 жыл бұрын

Easier? Yes, absolutely! As I say in the video, you may want to follow this guide to demonstrate that you can make a gaming virtual machine, do it as a passion project or want to test viruses i.e. the PUBG ransomware. You wouldn't want to do something like the latter on your main OS (or an OS that is part of a dual boot setup), as you wouldn't want to risk compromising your files, and as PUBG is a graphically intensive game, a gaming VM serves as a good way of testing that sort of stuff out. I understand the leap in terms of ease of access when it comes to this, though I have to say that this does have some perks that a dual boot doesn't necessarily provide.

I have no idea, probably not since the graphics card may be integrated with the motherboard so there's only one display output, not two (which is needed). If the BIOS doesn't allow you to change the graphics output (there probably won't be an option in your case) then you cannot use this laptop for this guide. Hopefully this helps!

Hmm, I'm no expert when it comes to this so I'm sorry if I can't help more than what I'll say here. I think you're using the NVIDIA graphics card on the Linux system when you shouldn't, hence why it would say NVIDIA is using the graphics card. The other ports mentioned could be the alternative DisplayPort/HDMI outs that can be seen in the NVIDIA control panel maybe? Anyway, what you should have done is enabled the internal graphics of your computer, change the output from PCI to the option that is not PCI in the BIOS and install Linux (preferably a minimal install) with these settings. That way, the Linux install outputs to the monitor that is connected to the internal graphics card and it also defaults to using the internal graphics instead of the NVIDIA graphics, so the process shown in the video works. Given your situation, I would advise you to check if this is the case and maybe reinstall Linux, as I know from experience if you change the output source in the BIOS it can lead to a looped boot sequence. If you go down the road of reinstalling Linux, it may help to not connect it to a monitor, as it should still show up when looking into PCI devices and it shouldn't install NVIDIA drivers. I'm not sure about how to get around this issue when Linux is installed, however. The only other thing I can suggest is to look into how to uninstall NVIDIA drivers in Linux, and maybe that would solve your problem. As I said, I'm no expert when it comes to this stuff! The whole point of this method is to passthrough 100% of a dedicated graphics card to a virtual machine, so using it in Linux is not what you should do. Installing NVIDIA drivers and all that defeats the purpose of doing this, which may have put you in the position you're in, though I wouldn't know! Hopefully this helps.

It depends on what you mean by 'main pc', if you mean the Linux hypervisor then probably not (the recording may have a lot of dropped frames and look rather crappy, as the work is being solely done by the processor), if you mean the Windows VM then I think you should be able to, as you would be able to make full use out of the RTX 2080 Super just like you would with a native Windows 10 install. It sounds like you have the specs to be able to play and record a game like CoD at the same time in the Windows VM, so I would suggest you give it a try and see how it goes.

so how do you use your graphic card on linux after you've done this?

@TheMaster974

4 жыл бұрын

Firstly, I thought it was supposed to be vfio_virqfo, as that's what SomeOrdinaryGamers said to do in his video about this (if memory serves). If it is meant to be vfio_virqfd then I would say that this is what everyone should be using instead! At the same time, I noticed I put 3 m's in iommu in the line above this (at this timestamp of 23:56) instead of 2, so I will also say it should be spelt with 2 m's and not 3! For the second point, you don't use your dedicated graphics card in Linux at all by following this process, as it will get locked out and passed through to a virtual machine. What I would say is to ensure you install Linux while the internal graphics of your PC is enabled and the output is changed from PCI to the option that is not PCI in the BIOS, so Linux gets outputted to the monitor that is connected to the internal graphics card, bypassing the dedicated graphics entirely (so you can possibly get away without connecting the dedicated graphics card to a monitor throughout this process). So, Linux only uses the internal graphics and not the dedicated graphics throughout this procedure, if that answers your question. If your question is how to use this is in a virtual machine later on, then watch the video up until around 33:00. If you want to use your dedicated graphics card in Linux after doing this, go into the grub file and remove the vfio-pci.ids line (at about 22:00), as this prevents vfio from grabbing the dedicated graphics card on boot. The point of this method is to passthrough 100% of a dedicated graphics card to a virtual machine, so using the dedicated graphics card in Linux is not advised. I hope this helps!
