This tutorial explains how to install and run Windows 10 on Linux using GPU passthrough and VFIO drivers to achieve near-native performance — for gaming, photo or video editing, and other graphics and CPU intensive tasks. It also lists the common pitfalls and possible ways to further improve performance. Last not least it offers a comprehensive list of external resources and helpful links.
You want to use Linux as your main operating system, but still need Windows for certain applications unavailable under Linux.
You need top notch 3D graphics performance under Windows for computer games, photo or video editing, etc. And you do not want to dual-boot into Linux or Windows. In that case read on. Many modern CPUs have built-in features that improve the performance of virtual machines VMup to the point where virtualised systems are indistinguishable from non-virtualised systems.
This allows us to create virtual machines on a Linux host platform without compromising performance of the Windows guest system. For some benchmarks of my current system, see Windows 10 Virtual Machine Benchmarks. The performance — both graphics and computing — under Xen and KVM has been nothing less than stellar!
How To: Patch Qemu and Fix VM Audio
The tutorial below will only work with suitable hardware! The tutorial is not written for the beginner! I assume that you do have some Linux background, at least enough to be able to restore your system when things go wrong. I am also providing links to other, similar tutorials that might help. See the References section below.
Last not least, you will find links to different forums and communities where you can find further information and help. Note: The tutorial was originally posted on the Linux Mint forum.

Over time, a wide variety of workarounds became popular, like passing through an audio interface, or using a usb sound card. This article will show you how to get the most out of your audio setup using nothing but software and the equipment you already own. Sinceit has most commonly provided the interface for audio device drivers: it supports a huge list of sound cards.
If your distro plays sound out of the box, you are probably running ALSA. On top of that we usually have PulseAudio, a sound server which comes pre-installed with most Linux distros. Using it allows for easy switching between multiple devices and regulating volume system-wide as well as per-device and each application individually. With interactive media like games in mind this potentially good practice as you shorten the processing pipeline by one instance and potentially reduce latency.
We will provide you with configuration samples for both use cases. Please check below for qemu arguments. In latethe reddit user Spheenik provided a patch for QEMU which dramatically improves its audio backend. Thanks to his work it is now possible to have well-functioning playback and recording inside guest operating systems.
The instructions in this section will attach your VM to PulseAudio. They are recommended for most users. Uncomment the line and add your user name here as well. They are recommended to more advanced users who want lower latency but also need to run applications depending on PulseAudio.
Follow the standard audio guide on the Arch Wiki instead. You need an additional qemu argument to make the passthrough functional:. Do you do prefer software or hardware solutions for your VM audio?

Running Windows 10 on Linux using KVM with VGA Passthrough
September 9th, 0 Comments. April 8th, 6 Comments.Now there may be multiple reasons for wanting to use a virtual machine. In my instance, I am using Ubuntu And on top of this, I have a virtual machine which uses Windows Many people have been wanting to switch from Windows to Linux, and this is something to ease the transition from one to another.
As for performance, I have a 3DMark Firestrike benchmark from a while ago on Windows 7 that scored When I benchmarked on my virtual machine that used GPU passthrough, it scored But aside from this, everything is the same, and everything is run at stock speeds. However at the time of writing, this list is rather short and does not list all supporting hardware. This makes things a bit more difficult as it does not state whether this support is for AMD-V or AMD-Vi as the latter is needed for what will be talked about later.
As well as your CPU, you must have a motherboard that satisfies two criteria. There are a few resources I used to find out whether my motherboard was able to support IOMMU, such as this post on overclock.
I also checked my motherboard manual, which did confirm it supported VT-d. The reason why it must support two GPUs is so you can have one for your host machine, and passthrough the other to your VM. Even using onboard graphics or the iGPU should be sufficient as your host machine graphics adapter.
In my case, the GPU for my host machine is my Intel integrated graphics, while I will be saving my discrete video card for my Windows machine. If you were to have two video cards on your machine, you would be able to pass only one of them for use on your host machine, and use the other in your VM. This is not a requirement for the method I am using, but I will explain the extra steps needed so the VM works optimally.
KVM GPU passthrough on a Windows VM
If you wanted to, you could put everything on a single hard drive. Then I have one final directory which will contain my Windows image. If anyone is using an MBR on their disk, they will be limited to having four primary partitions, which for this project should not be a problem. However if you need more partitions, you should consider making an extended partition, which will allow you to have more partitions without going through the process of converting to a GPT partitioning scheme.
Either way, you should be fine.Work fast with our official CLI. Learn more. If nothing happens, download GitHub Desktop and try again.Ldk retrofw

I will compare spice server, pulse audio and a hardware solution. A common issue with sound passthrough between guest and host is lagging or chopped up sound playback. In order to fix this make sure the host and the guest use the same default playback sample rate.
This one is pretty straight forward, open the info page of the VM on virt-manager and add a spice server. Adding the spice server adds actually several devices to the VM config, one for example is a display. Basically it is double clicking on the running VM in the virt-manager list. If yes make sure to add these options:.
Make sure no further audio devices are added by virt-manager — remove all audio devices from the virtual hardware details bar left side in VM info view. It creates awful stuttering and performance loss. Use ac97 audio devices instead.
If the sound distortions occur, make sure host and guest run at the same sample rate. The glorious arch-wiki. Users spheeniks reddit post. Reddit post for audio problem with QEMU 4.
Thank you for this tutorial, I finally understood why sometimes I had the sound of my VM with my headphones. Any idea how to fix this? Do you use discord on the host, or on the guest? I just wanted to thank you for your tutorial, it helped so much setting up my passthrough setup so I can finally make the switch to Linux full time.
Thank you for the kind words, means a lot. The whole idea is to pave the way for people to switch to Linux.

This can be inconvenient if you're still tweaking the config. Some guides and tutorials will use virt-manager. Since my Linux install is rather lean, I've done all of the configuration by hand and won't cover virt-manager here. Configure the options for your VM in start.
This script is highly dependent on your hardware and host OS, and it's advisable to go through it line-by-line to understand what options you're passing to QEMU.Agnello con carciofi e patate al forno
The old way of using -usbdevice has been deprecated. Ideally, use the qemu-xhci controller device qemu This can be problematic in non-obvious ways: for example, if you wanted to connect and use an Xbox Controller for Windows, Windows 10 might recognize and install drivers for the Xbox Controller but won't initialize it properly Code Getting audio working on the guest was a bit tricky.
You might face some issues with scratchy, delayed, or even loss of sound, most of which I won't cover here since I did not experience it. Note : Having multiple sound devices 3 and 4 seemed to result in audio intermittently working, with either lots of lag or no sound at all.
There is some issue with drivers, latency, audio buffers, and timing, but what I found solved this issue was to have only one device enabled in the start script at one time.
In my case, I disabled passing through the audio device on the graphics card and only passed through the USB headset: all works well now.
You'll want to be mindful of any additional computations on the host or other VMs that aren't pinned. For example, if you run a heavy job on the host without specifying which CPUs it should or shouldn't use, you'll start sharing with the Windows 10 guest, leading to terrible performance on the guest.
The following sections are some configuration settings that I use. We can use hugepages to reserve a certain amount of RAM for the guest's exclusive use. Increased performance.Fso ka full form
Some documentation. Run as root. There is a way to run it as a less-privileged user, but I haven't gotten around to configuring that yet. Load the Windows 10 installation ISO and virtio-win.
In the Windows 10 install process, you might need to load device drivers before it recognizes your disks. There doesn't seem to be a good way to configure the Samba share with anything more complex than one folder. Although not recommended, you could modify the ephemeral config after the guest has started and reload smbd.
If you need finer controls in file sharing, it seems best to run a proper Samba config and restrict access to the loopback interface for guest-OS-only access. On occasion after some hardware changes, Windows will be loaded directly. Skip to content.Ask Ubuntu is a question and answer site for Ubuntu users and developers.
It only takes a minute to sign up. In VBox and VMware, all you have to do is install the guest additions, then everything will work including the display, folder sharing, etc. I would like to have a Windows guest either 7 or 10 with at least a working network, display drivers, and folder sharing. Setting a Filesystem passthrough does not seem to work in Windows guests and I also got sick and tired of trying Samba to work. What's the proper way to create a Windows guest with working display and sharing?
Maybe I missed some dependencies or Virt-Manager specific settings? Sadly, no 3D acceleration support for Windows guest OS Install and verify KVM :. For the Network driver, you'll probably don't see any listed drivers while loading it during installation. If that's the case, then you can manually update the driver later on. Install and configure Samba for basic public folder sharing over network:. Downloading spice-guest-tools-latest. Note that KVM does not provide file sharing to Windows guests.
You still need to set up Samba yourself for that. Maybe for future readers, about the file sharing part, you can also see it the other way round. Create a share on the Windows VM and mount the share on your Linux host.
This is easier to setup no need to setup a samba server on the hostbut needs the folder to be mounted after the VM started. Good for occasional use, not ideal for daily use. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top.
