If you find glaring errors or have suggestions to make the process easier, let us know on our discord. The exact name and locations varies by vendor and motherboard. Systemd-boot distributions like Pop!

OS will have to do things differently. You can also just run lspci -nnk to get all attached devices, in case you want to pass through something else, like an NVMe drive or a usb controller. Look for the device ids for each device you intend to pass through, for example, my GTX is listed as [10de:1b81] and [10def0] for the HDMI audio.

Mac OS VM Guide Part 2 (GPU Passthrough and Tweaks)

If two devices you intend to pass through have the same ID, you will have to use a workaround to make them functional. Check the troubleshooting section for more information. Save and exit your editor. This path may be different for you on different distros, so make sure to check that this is the location of your grub. The tool to do this may also be different on certain distributions, e. If the GPU and your other devices you want to pass to the host are in their own groups, move on to the next section.

If not, refer to the troubleshooting section. Run dmesg grep vfio to ensure that your devices are being isolated. From here the process is straightforward. Start virt-manager conversion from raw qemu covered in part one and make sure the native resolution of both the config.

Repeat for each device you want to pass through. Remove all spice and Qxl devices including spice:channelattach a monitor to the gpu and boot into the VM. You can switch your network device to macvtap, but that isolates your VM from the host machine, which can also present problems. If you use wicd or systemd-networkd, refer to documentation on those packages for bridge creation and configuration. From there all you need to do is add the bridge as a network device in virt-manager.

Not everyone uses a full desktop environment, but you can do this with nmcli as well:. Next, run these commands, substituting the placeholders with the device name of the network adapter you want to bridge to the guest.

They create a bridge device, connect the bridge to your network adapter, and create a tap for the guest system, respectively:.

You may need to restart network manager for the device to activate properly. NOTE: Wireless adapters may not work with this method. Check for these by running iw list. From there you can set up a virtual AP with hostapd and connect to that with the bridge. This is also the best way to get AirDrop working if you need it.

If all else fails, you can manually specify routes between the host and guest using macvtap and ipor set up a macvlan.

Both are complex and require networking knowledge. Emulated input might be laggy, or give you problems with certain input combinations. This can be fixed using several methods. This method is the easiest, but has a few drawbacks. It may also need to be adjusted if you change where your devices are plugged in on the host.

Just click the add hardware button, select usb host device, and then select your keyboard and mouse. When you start your VM, the devices will be handed off. This method uses a technique that allows both good performance and switchable inputs.

Totally high fidelity. No lag at all. Very HD. This is probably some minor issues with my config. Will update this post with the details of how I did it as soon as I can. Oh yes, I got all three of Gentoo, High Sierra and Windows 10 Enterprise all running at the same time on this single machine right now, and they are all running at very near native or native speed.

In theory achievable; but would require purchase of a second AMD card. Rationale "Why? Jokes aside, a bit of a brief background -- this whole trouble started with my Apple Magic Mouse Series 1. I really love this mouse -- it has been with me almost 8 full years now, and yes, it still looks beautiful; and I really wanted this wonderful mouse to work in an acceptable manner in Gentoo Linux. I managed to get it to work, but somehow the scrolling and movement in X Window just does not "feel right," even if I tried tuning it with xinput.

But the scrolling and "feel" are still somewhat "off". Which brings us to this point. From OCD my perspective, this is all done just to get the mouse to work "right" on my setup below. The NVMe M. I compiled Linux Gentoo 4. I also compiled QEMU 2. Discussion: To get High Sierra Was I repeating myself there? That is the trouble with OCD, there is this irresistible compulsion to do a certain thing in a specific way.

OSX GPU passthrough to Windows

I have tried many other methods, but presently it seems that the instructions in the above GitHub link are the only ones that worked. All that is needed is to hex-modify the binary so that the hardware layout of the RX is correctly reflected the binary file in that kext.

It is unclear whether a is needed if b is done -- I have not tested such scenario. Specifically, this is what I changed in the binary using xxd: For the "Acre" personality located at 0xf80 in the binary file, change the hex from to this All the connectors DP, HDMI, DVI at the back of the card now work perfect.

The result is that bluetooth and all my USB ports I have not tested the 3. I would then control the Linux host underneath via ssh from the High Sierra guest. When the Dell monitor is dedicated to the High Sierra guest at full 4K, the linux host basically becomes transparent and invisible to the user.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.

Ubuntu and KVM: UPDATED Easy GPU passthrough guide

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!

In Intel jargon its called VT-d.That's all running quite well. That leads to issues when running GPU intensive applications obviously. Does anyone know if the pro version, or some version of VMWare Workstation would let me do this? I know that ESXi does, but I don't want to turn my entire home computer into an ESXi host, nor do I have the money to buy a home server or powerful enough workstation to set this up on. Are there any options that won't break the bank for home use that will allow me to share my GPU power with my guest VM?

Whatever you are trying to do, you can't do this on the host directly? Any reason you want this at the guest level? Unofficially, I have heard folks trying this successfully on Win8 x64 machines. Have not tried it on 8. A note though, 6. Generally speaking, ESXi can't power on a VM with a virtual hardware version that is higher than what it supports. Check the chart here. Workstation full edition does not have the word player in the title, and supports 3D acceleration.

Consider supporting us on Patreon if you like our work and want to see more from us. First, install a few prerequisite packages.

So run:. Make sure to do this in a working directory where you want the VM files to live. The jumpstart script defaults to If you would rather install mojave, or high sierra, just run it with the corresponding argument, e. The jumpstart script should make the recovery media for your VM to install from. After it finishes, simply create a qcow2 image by running.

You may also want to change the mac address listed in line 23 -device eem Your vm should, after a short while, boot into clover, and then an OS X recovery partition. Be sure not to format the recovery disk or the small partition labeled ESP. This bit can take a while. From here, there are a few common tweaks you may want to do to improve performance and useability:. Start by copying ESP.

Do the same for the firmware folder. From there, boot into the VM, open a terminal and run sudo diskutil list. The MB disk is the one you want. Mount its first partition by running sudo diskutil mount diskXsY where X and Y are the disk and partition numbers. There should be a section of this file that looks like this.The intent of this document is to provide a complete, step-by-step guide on how to setup a virtual machine VM with graphics cards GPU passthrough — detailed enough that even Linux rookies are able to participate.

The final system will run Xubuntu The article is based on my last years guidewhich used Ubuntu I am still very happy with my distro choice Xubuntubut I have to emphasize that X Ubuntu or any Debian based distro is not the easiest distribution to perform virtual machine passthrough.

Most of the guides I found online were targeting either Fedora or Arch as the host operating system. Especially Fedora 26 should be easy to setup for passthrough as recommended by level1techs. Virtual machines with set up GPU passthrough can gain close to bare metal performance, which makes running games in a Windows virtual machine possible.

Unfortunately, the setup process can be pretty complex. It consists of fixed base settings, some variable settings and several optional mostly performance settings. In order to sustain readability of this post, and because I aim to use the virtual machine for gaming only, I minimized the variable parts for latency optimization. The variable topics itself are linked in articles — I hope this makes sense. In order to successfully follow this guide, it is mandatory that the used hardware supports virtualization and IOMMU groups.

When composing the systems hardware, I was eager to avoid the necessity of kernel patching. The ACS patch is not required for the given combination of processor and mainboard. I installed Xubuntu I used the 4. Update — since version Any kernel version from 4.

In Ubuntu Ubuntu If you want to use a newer version, you can build it on your own. I have created a seperate article on the update process under Ubuntu.I came from a hackintosh, but got tired of the fragility of some upgrades.

Officially, only on Apple host hardware i. There's an explicit "am I running on Apple hardware? DrDonk's unlocker on GitHub is what you need. I expect this will still work okay with generated data if you follow hackintosh guides. Recently I moved my boot drive to a passed-through NVMe for extra speed.

My other drives are ESXi virtual drives backed by storage elsewhere on my network. Kepler generation cards are the last to work out of box, and the only to currently work out of box on Mojave. If you don't need hefty performance, a GeForce GT is a cheap card. I recently spent awhile trying to figure this out, going so far as to write my own SSDT tables for the device, but finally gave up. And finally, on the context of this whole thing--I switched from a real Mac Pro to a hackintosh years and years ago, when it became clear Apple didn't care about upgrading the hardware.

They still don't. The last Mac Pro release was the iPhone was a 5S! They've been promising things will improve "soon". They're the world's most valuable company; if they actually cared, at the organizational DNA level, it would have happened by now.

I remember a long time ago maybe close to a decade? I was looking into this a bit because I was interested in iPhone dev, and the requirement that that toolchain use Mac hardware was hard for me to swallow. It still seemed fairly hacky at that point, and ultimately I wasn't willing to shell out hundreds of dollars for a dev license and hardware just to see if it was worth it and I wasn't willing to go that far into the weeds on a commercial closed source platform where any problem I might have would likely be ignored with prejudice.

It's good to know they support some form of virtualization now. Do you know it they support any of the consumer grade virtualization systems?

Even if I had to pay for a full macOS license I think it wasn't nearly as cheap then either and a developer license, that would have probably been much easier to swallow, and could have led to more hardware investment from me later if things worked out.

Apple hasn't charged for macOS or updates for at least a few years now. Their license text includes references to volume licensing, but I guess that's for very large-scale companies with direct contacts.

Can you please elaborate on your GPU passthrough setup? Those checks are at the driver level, and only for Windows you can circumvent them by not exposing VM cpuid details to the guest. On macOS I haven't done anything special.

Even on real Mac Pro hardware, those drivers are notoriously bad. Windows is a different story, and I had to use a patched vBIOS[1] to get my working without Windows 10 throwing the dreaded "Code 43" error when it detects virtualization and refuses to work.

SXX on Aug 15, This was only the case up to Haswell CPUs. Hi Matthew, I'm very interested in your setup, since I've stability issues with my Hackintosh. May I contact you in private? Fnoord on Aug 16,
