I’ll just say that I don’t think you’ll ever get stability with 8gb for win 11
First, I’ve never tried using Linux as a VM host, so there might be something in play I don’t know about. However, having run Windows 11 as a guest under Windows 11 and macOS, I can push Windows 11 down to 1 GB of RAM With no problems. It’s a little sluggish when opening apps but never unstable. Normally I run it with 4 GB.
