I install dockur windows on github codespace it works perfectly, turns out the /dev/kvm is a actually directory, but the problem is if you try to custom the Windows novnv under the environment: you'll keep getting an error even if you add - infront of

environment:
USERNAME: "example"
PASSWORD: "examplepassword"
RAM_SIZE: "5g"
CPU_C0RE: "4"
LANGUAGE: "English"
KEYBOARD: "en-US

Even replacing the " : " with " = " you still get errors

Make a post about your problem with kvm on Stack Overflow make sure it is a detailed as you can make, I recommend adding screenshots on post to get more useful answers

Is anyone of you using Docker Desktop for Linux? Because it does not support KVM, only the Docker Engine does.
