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

Follow dortania then this https://github.com/5T33Z0/OC-Little-Translated/tree/main/01_Adding_missing_Devices_and_enabling_Features/CPU_Power_Management/Enabling_XCPM_on_Ivy_Bridge_CPUs then try boot again

See https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/Ivy_Bridge-Ventura.md if you want electron apps, updates, filevault and everything working.

From the link you did provide I handle you this:

Also, check if you need this SSDT: https://github.com/5T33Z0/OC-Little-Translated/blob/4ef2d13a477de448e8f5337604602b668d9281c4/11_Graphics/GPU/GPU_undetected/Readme.md

Hah, Common mistake, but easily fixable. Follow the ACPI guide. It's not perfect, but it covers all the basics you'll probably need. If you're interested in more, check out OCLittle's guide (translated by another user). The files are a bit outdated, but the explanations are great.
