In the annals of operating system history, few names evoke a sense of wistful "what if" quite like Windows Longhorn.

This command creates a 50GB QCOW2 image. Adjust the size according to your needs.

qemu-system-x86_64 -hda longhorn.qcow2 -cdrom path/to/longhorn.iso -m 2048 -smp 2

Adjust the -m and -smp parameters according to your system's capabilities. qemu-system-x86_64 -hda longhorn

Because Longhorn pre-dates VirtIO, the following legacy hardware emulation was required:
