: If you are using KVM, QEMU, or Proxmox, you must also download the VirtIO drivers (usually an ISO from the virtio-win-pkg-scripts GitHub ) so Windows can recognize your virtual hardware during and after installation. 2. Create a QCOW2 Image from an ISO
Leo rubbed his eyes. His MacBook Pro was a beast—M3 Max, 96GB of RAM—but it was a walled garden. For the past six months, every software dependency he needed for his legacy robotics simulator demanded a Windows environment. Not a virtualized one. Not the slow, chunky VirtualBox version. He needed bare metal feel inside a container.
