> Running Windows or Linux as a VM in macOS has terrible performance in VirtualBox right now (people are discussing it at length in VirtualBox forums). That's my experience as well. Running macOS VM is even worse. My understanding is that it's because all of these rely heavily on 3D acceleration for the GUI and VirtualBox's acceleration support has not worked properly for a few years now. It's slightly better if you run VirtualBox in the low resolution mode but still not ideal (and of course the graphics are... low resolution). It's quite obvious that macOS hosts are not a priority for Oracle, I mean, a few VirtualBox releases couldn't even be installed (missing notarizations and one other occasion I cannot remember right now) and Oracle noticed only after people started complaining on the forums... These says I use VirtualBox but in the headless mode and I connect to it via SSH and VS Code's SSH remote extension.
