QEMU
Software that emulates a whole computer, so an operating system can boot and run inside a window instead of on real hardware.
QEMU pretends to be a full machine — CPU, memory, disks, network — letting you boot and test an OS safely without touching physical hardware. It's the standard tool for OS development because you can restart, inspect, and debug freely. 'Over QEMU NAT' refers to its built-in virtual networking, which routes the guest OS's traffic out through the host.
