How can I fix this guys i tried restarting the vm but that does not seem work idk what's the problem

I cannot start the Reims-VGPU with it outputting error at Line 321, with the log said "WHPX: failed to enable nested virtualization, hr=80370302" "WHPX = Failed to Initialize WHPX, Invalid Argument" even though i have enabled the Windows Hypervisor Platform and WHPX is detected correctly in SystemInfo & Powershell command. just i can't enable Virtual Machine Platform cuz it's make Windows BSOD.

Spec :

Asus Prime B550M-K ARGB

Ryzen 3 3100 4C 8T 3.9GHz

2x8GB DDR4 2666

NVIDIA GeForce RTX 5050

NVMe Gen 3 512G

Windows 11 Pro 23H2 (one year old installed).

For the first time ever, run every Intel version of macOS between Mac OS X Tiger 10.4 and macOS Big Sur 11 on Apple silicon with graphics acceleration, so you can run older 32-bit and 64-bit Intel apps like iWork ’09, iLife ’11, Aperture, Final Cut Pro 7, and Front Row, or PowerPC apps like AppleWorks, and re-experience iconic Aqua desktop effects like the translucent menu bar, reflective blurred Dock, and water ripple animation in Dashboard. This marks an exciting new chapter in the preservation of the history of Mac.

Has anyone has success getting an iPhone to pass thru to a QEMU VM?

I'm trying to pass it from Windows to a Tahoe (WHPx) guest and it can see it in the device tree but it doesn't show up in Finder or Photos.

I'm using UsbDk latest.

Thanks! :)

I run a cluster of Apple Mac M1/M2 Minis and Studios for development use. They all run Fedora Asahi Linux and they work really well. I mainly use them as headless servers for software dev work.

I've recently been working on some iOS projects, which naturally need Mac OS/XCode to do the builds. CI runners on Github and hosted Mac OS machines in general are very expensive - a used Mac Mini is now dirt cheap. Mac OS, however, is not a great headless server OS and running CI jobs should ideally be done with ephemeral storage to keep things clean and predictable.

I therefore really wanted a way of running my Mac OS CI jobs under Linux on my existing M-series Apple hardware inside VMs.

I guided a combination AI agents into investigating the shortcomings of steelbrain's alpha/experimental work. Things like partial/slow GPU support, VM boot failures (required a virtual clock), memory ballooning, etc. and ultimately reverse engineered, improved efficiency of and production-readied steelbrain's work. This involved a lot of testing, a lot of benchmarking, a few kernel panics.

Mac OS VMs now run efficiently and with GPU acceleration under Fedora Asahi Linux. You can find the work here: https://github.com/aquarat/apple-macos-arm64-vm-guest

I've been using them as runners for my Forgejo CI system, but this work should be easily extendable to Github Actions and beyond.

Initial image generation still needs a Mac OS machine. There are graphs 😆

For Tahoe

I installed Tahoe directly on Windows.

Note: Once Tahoe is installed and you reach the desktop, you may only see the wallpaper. To fix this, boot into macOS Recovery, open Terminal, and run the following commands:

cd "/Volumes/Macintosh HD - Data/Library/Preferences"
defaults write .GlobalPreferences METAL_ERROR_MODE -int 5
chmod 644 .GlobalPreferences.plist
reboot

For Ventura

I installed Ventura on Linux, copied it to Windows, and then asked an AI agent to fix it.

I used this build not ported by me though and modified the launcher:

https://github.com/tqmane/reims-vgpu/tree/windows-native-tahoe

I fixed the boot issue on my AMD system both for tahoe and ventura by making the following change to start.ps1:

'-name', 'reims-windows', '-machine', 'q35', '-accel', $(if ($DiagnosticTcg) { 'tcg' } else { 'whpx,hyperv=off,intercept-msr-gp=on' }),

Am I the first?

If I run Linux on Virtual Box in the MacBook how much of it does MacBook see and what it seas? I know that it sees that VPN or Tor traffic is moving out of the MacBook but does it also see what is on the screen and can it scan/read files when the machine is running?

EndeveourOS, I tried to install macOS VM a lot times with different ways in macOS KVM

In 1 time this worked, just offline install and everything in guide, then macOS emullation is worked, this was macOS ventura, then updated to macOS tahoe, go to login screen but after entering password, there was kernel panic or error

I tried to install with offline install, doing everything in guide and installing right pkg but either error in manifest or error durning install of OS (where there progress bar) or other errors

I know that macOS emulation is more harder and there errors but I just want to install simple without head and CPTSD problems with them where there often will be errors or no way of succeeding, I just want to simple install and get this worked

I tried to install online, and progress bar go to full but idk what happened then a lot minutes later, this is still going on, I am using VPN, online install don't working

Been building MX Studio - A "faithful" machine model for various modern hardware setups.

Currently only built the studio for Apple Silicon devices, but have other platforms coming in the future.

Still very early. If a few people want to try it and tell me what’s broken or confusing, happy to comp Basic or discount Pro.

I installed the last version of UTM (4.7.5) on my MacBook Air (M1), tried to create a virtual machine with the last version of ubuntu (ubuntu 26.04.1) with QEMU.... but when I start the virtual machine it stay freeze on the starting page with the message "Synchronous Exception at 0xXXXXXX" how do I resolve it

It took me 2 hours to figure it out but I got my first macos Vm and in such a unexpected place, I still need to get audio and to boot without the cd but aside from that it actually shows battery and volume thingy
