I'm having trouble with PCI Passthrough and Sierra/High Sierra on a GTX 1050. I installed the latest Web Driver, but I get freezes of the GUI after installing it.

 

It seems to work fine for OpenGL, it's just any app I launch, or quit, makes the system freeze while it's opening and closing, Safari is the worst offender.

 

My qemu launch command is:

#!/bin/bash
MY_OPTIONS="+aes,+xsave,+avx,+xsaveopt,avx2,+smep"

~/QEMU/bin/qemu-system-x86_64 -enable-kvm -m 3072 -cpu Penryn,kvm=off,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,$MY_OPTIONS\
	  -machine pc-q35-2.9 \
	  -smp 4,cores=2 \
	  -vga none \
          -usb -usbdevice host:046d:c534 \
	  -device vfio-pci,host=24:00.0,bus=pcie.0,multifunction=on \
	  -device vfio-pci,host=24:00.1,bus=pcie.0 \
	  -device isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" \
          -drive if=pflash,format=raw,readonly,file=./OVMF_CODE.fd \
	  -drive if=pflash,format=raw,file=OVMF_VARS.fd \
	  -smbios type=2 \
          -device ide-drive,bus=ide.1,drive=MacHDD \
	  -drive id=MacHDD,if=none,file=./mac_hdd.img \
          -netdev user,id=usr0 -device e1000-82545em,netdev=usr0,id=vnet0 

I've tried with kvm=on and kvm=off, it didn't seem to change anything. I also installed Lilu and NvidiaGraphicsFixUp, but I'm not sure they are working/Loading, as when I run kextstat | grep lilu it doesn't return anything.

 

The same setting work fine for Windows 10, everything works as expected.

 

EDIT, seems to be a problem with Metal, I removed the GeforceMTLDriver Web, and now things run fine, albeit without Metal Support, in OpenGL mode.

 

I think the GTX 1050 I have is a new card Device ID 10de:1c81, the latest Clover doesn't have a Dev ID of it, so maybe there is hope that nVidia will fix the Metal support for it.

I spoke too soon, the machine was fine on first boot, then the same deal again after I rebooted. Also it seems the stock GerforceMTLDriver, not the web, is also in use, because if I remove it, the system doesn't produce the GUI anymore.

I am having a heck of a time getting my USB Controllers to work in my VM. I see others are having success. Can someone help?
 

I have successfully passed the controllers into the VM, both show up in DCPIManager.

 

1) Integrated USB controller 82801JI (ICH10 Family) EHCI Controller #2

 

DCPIManager says it is loading AppleUSBEHCIPCI.kext
But OS X sees nothing attached. No power to devices.

 

2) VIA Technology USB 3.0 (native support)

 

DCPIManager says it is loading AppleUSBXHCIPCI.kext

A USB flash drive works fine. The drive is mounted and ejects fine.

An apple mouse does not. I plug in the mouse and it blinks red a couple times and then stops blinking.

A Microsoft webcam (native support) appears attached but continually disconnects and I am seeing, when attempting to use the video/audio, on my host logs:

Nov 19 00:42:06 pve kernel: DMAR: DRHD: handling fault status reg 2
Nov 19 00:42:06 pve kernel: DMAR: [INTR-REMAP] Request device [04:00.0] fault index 1f [fault reason 34] Present field in the IRTE entry is clear
Nov 19 00:42:06 pve kernel: DMAR: DRHD: handling fault status reg 102

None of these problems are present on my windows VM with nearly identical config. Both USB controllers work flawlessly. Every device attached to them work flawlessly. And I know these devices work when attaching them to my physical hack.

 

My video and audio (also ICH10) are working via passthrough into Sierra.

 

I believe its a DSDT issue because I am also having problems when passing USB devices/ports individually without PCI passthrough. No devices appear under the standard USB IO names EHCI/UHCI/XHCI in ioreg.

 

Also the devices do appear to be powered up in Clover. The problems happen when loading Sierra.

 

I don't know what else to try. Please let me know if you can think of anything I can try. Thanks!

I believe it is a DSDT issue because I am also having problems when passing USB devices/ports individually without PCI passthrough.

 

Only USB 1.1 devices can be passed to a macOS guest without the PCI passthrough of a corresponding USB controller. For USB 2 and 3 devices, PCI passthrough of the corresponding (and supported) USB controller must be done.

Hi,

 

I got my macOS Yosemite VM working with GPU passthrough like 2 years ago by reading this thread.

 

I don't use this VM much, only when photo editing in Lightroom.

 

So I just tried to start it but it stops at this message in the QEMU window:

AppleCredentialManager::start called
AppleKeyStore starting (BUILT: ...)

Except of updating my Ubuntu machine from 17.04 to 17.10, I don't think I changed anything in the launch script.

 

Interesting thing, if I remove the two lines for VFIO gpu passthrough and add a qxl device, then I get a working macOS Yosemite in a QEMU window with 800x600 resolution only.

 

What's wrong and what can I do?

 

Thanks.

 

Here is my script:

sudo sh -c 'echo 1 > /sys/module/kvm/parameters/ignore_msrs'

I try to run macOS High Sierra with QEMU and NVIDIA passthrough but getting black screen on boot. I can see the Apple boot logo going to about 75%, then turning off all 3 monitors (2x DVI, 1x HDMI). I cannot access remote display but ssh shell (see below).

Same config works with Win10/7 passthrough.

 

Installed latest Nvidia Web Drivers for 10.13.3. Latest Clover 4380.

CPU Core I5, GPU GTX 970

 

QEMU line is:

I have created a 10.13.3 install image, and installed to a 128GiB qcow2 image, using the Kholia/OSX-KVM boot-macOS-HS.sh script, doctored to use a bridge network interface, but I can't boot with a passthrough, and the libvirt image doesn't want to boot, either.

The non-working boot-passthrough.sh script I produced:

And the libvirt script fails to boot it. I modified it to use 4 core, 8 thread, host CPU (i7 3770), no virtual graphics, passing through all of the devices mentioned above, and it simply boots to the Tianocore logo, spinning all 8 threads, then eventually getting stuck spinning only one core, without actually hitting Clover.

 

I notice the libvirt scripts have been updated, but the boot-passthrough.sh script hasn't been updated in a few months.

 

I would prefer to get this working with the libvirt method, as that's what I use to maintain my other virtual machines, including automatic startup on system boot, and automatic shutdown on host reboot or shutdown.

You must always set the CPU to Penryn; otherwise, Clover won't work. Also, make sure you are using the premade Clover image and OVMF_CODE file from the OSX-KVM place.

 

There are issues with the recent version of Clover and OVMF that prevent you from booting a Hackintosh install on qemu.

You probably need to using modprobe to load the vfio-pci driver and manually bind the GPU to VFIO:

 

echo "1002 6719" > /sys/bus/pci/drivers/vfio-pci/new_id

echo "0000:01:00.0" > /sys/bus/pci/devices/0000:01:00.0/driver/unbind

echo "0000:01:00.0" > /sys/bus/pci/drivers/vfio-pci/bind

echo "1002 6719" > /sys/bus/pci/drivers/vfio-pci/remove_id

 

echo "1002 aa80" > /sys/bus/pci/drivers/vfio-pci/new_id

echo "0000:01:00.1" > /sys/bus/pci/devices/0000:01:00.1/driver/unbind

echo "0000:01:00.1" > /sys/bus/pci/drivers/vfio-pci/bind

echo "1002 aa80" > /sys/bus/pci/drivers/vfio-pci/remove_id

I managed to get it working, both with the distribution stock OVMF and the repository supplied OVMF. The issue with that was replacing the VARS image with the one matching the correct CODE image, or else it wouldn't boot at all.

Note the overriding CPU flags. I also had to leave out AVX2, since my CPU doesn't support that.

 

It boots, it gets past hardware enumeration if I set Clover to boot in verbose mode, but when it gets to loading the hardware drivers, it fails to attach either my display or my USB interfaces, leaving them in a seemingly detached state. The displays shut off, the USB mouse disconnects, but my USB keyboard appears to recognize caps lock and toggles its state LED. There doesn't appear to be much I can do with the machine at that point.

 

E: I managed to get it to boot, by configuring Clover with Graphics > RadeonDeInit, but now I have stuttering audio that I did not experience under my Windows VM. I assume that this stupid thing is too sensitive and needs CPU core isolation, which is total bullpucky.

As I don't get gpu passtrough anymore on Ubuntu 17.10 I'm trying to update my setup by following instructions there: https://github.com/kholia/OSX-KVM

 

The problem I have is that it's getting confusing over there as instructions for Enoch bootloader, UEFI/Clover bootlaoder and High Sierra are multiplying and getting mixed in cross-references.

 

With this post I'm trying to eliminate unknown variables from the equation.

 

First, I'm trying to figure out if the patched QEMU is still needed.

This step is not optional and is required. QEMU 2.10.1 shipped with Fedora 27 works fine too

Ubuntu 17.10, which was not yet released when most of these instructions were written in August 2017, now also ships with QEMU 2.10 as Fedora 27.

 

Anybody on Ubuntu 17.10 can tell me?

Put the included q35-acpi-dsdt.aml file into EFI/CLOVER/ACPI/origin location

This is in UEFI instructions but not in High Sierra with Clover instructions. Is that still necessary?

 

 

Thanks all
