KVM-Opencore VS OSX-KVM

The EFI folder is the same as v20 here

If that's my OpenCore ISO, I rechecked High Sierra recently with v18 and it boots fine.

The mid/hard way would be to have a powerful PC like I did recently, switch to Linux as the host, and use it as your main OS and then for specific stuff, turn on the Windows or OSX machines. The problem here is that you have to deal with Linux and its quirks... editing files with the terminal, sudo, setting up QEMU, editing the libvirt XML files (or create your own bash scripts for QEMU) and so on... It feels like a hassle sometimes, and getting OSX to work in a virtual environment is a hit or miss - there's a few projects out there that can help) but then getting them to work is like running a command and having it contained in its own "window" and you can also share files between the host and the VM almost seamlessly.

What are you using to create VM? You don't need to configure these two: macOS Simple KVM OpenCore KVM

Yes, I recently had to compile some stuff on Windows (I'm on an AMD Linux host) and VirtualBox just wouldn't start Microsoft's Windows dev VM (the one they provide for free for Virtualbox). I ended up learning how to use qemu and it works great...and as a bonus I was able to run a hackintosh (via https://github.com/kholia/OSX-KVM) and it works near flawlessly, which was something I was never able to accomplish with Virtualbox (granted I haven't tried in a few years).

I'm pretty happy with Qemu now, even if it's jsut a CLI interface. I was tempted to try the virt-* stuff, but honestly it seems like one more thing to learn so I'm going to hold off until I need something like copy/paste between VMs and can't figure it out in qemu direct.

Working on a patch to include it as a flake input instead of vendoring it in the repo, so this should no longer be true. I use the QCOW2s for OpenCore from osx-kvm that I have not figured out how to reproduce yet https://github.com/kholia/OSX-KVM/blob/master/OpenCore/OpenCore.qcow2

For almost a year, I have been coding a little project in Python intended to piggyback on the framework of kholia's OSX-KVM project, known as ultimate-macOS-KVM, or ULTMOS.

I just researched a bit, mac os x guest vm with pcie passthrough seems possible on linux.

Dropping the links below:

VirGL is definitely an interesting project, but all one has to do to get GPU passthrough working (from a Linux QEMU host to any guest OS) is: 1.) research a cheap, secondary GPU that is natively supported by the guest OS, 2.) plug such a secondary GPU into a PCIe slot on the host and hook it up to the primary monitor with a secondary cable (D-Sub vs. DVI, etc.), 3.) setup Linux to ignore the secondary GPU at boot and configure a QEMU VM for the GPU passthrough. The whole process takes perhaps one or two hours and as works flawlessly, with no stability issues. (Switching across the two GPU cables can be accomplished in software by using Display Data Channel /DDC/ utilities and switching keyboard/mouse can be accomplished by using evdev /event device/ passthrough.)

I get "verification failed" error when using https://github.com/kholia/OSX-KVM

I also see there is KVM-OSX which looks to be actively maintained, but I haven't heard anything about it.

You can use qemu/libvirt/kvm on any Linux host to run macOS pretty easily these days[1]. I run Ventura on unraid with nvidea gpu passthrough and it’s been fairly painless.

You can also run macOS in docker, but it’s ultimately running through qemu/kvm as well[2]
