The QEMU Advent Calendar website features a QEMU disk image each day of December until Christmas.

Each day a new disk image file becomes available for download. A QEMU command-line is posted along with the disk image file as the recommended way to start the disk image.

The disk images contain interesting operating systems and software that runs under the QEMU emulator. Some of them are well-known operating systems, old and new, others are custom demos and neat algorithms.

The disk images are created by volunteers from the QEMU community to showcase cool software that QEMU can run.

PS: There are still some slots, if you are interested in contributing any fun disk image, feel free to contact ([email protected] or [email protected]) or find us on #qemu on IRC on OFTC
