	You can run [[Emulator image files]] of almost any version of Sugar and the XS school server in qemu, including daily builds, releases, Sugar on a Stick, Live CDs, sugar-jhbuild, and whatever else we come up with. As we [[port Sugar]] to other computer architectures, such as [[~~ARM~~]], this will become increasingly important, so that developers and testers do not have to purchase one of each.

This includes software that is incompatible with your operating system, and software for different processors. Other options are [[VirtualBox]] (Free Software) and ~~VMWare~~, commercial software with a no-cost runtime version.

			==qemu monitor==

			The key combination Ctl-Alt-2 (not F2) transfers you from your running virtual machine to the qemu command line. This lets you query the system, save and load snapshots, and perform other administrative tasts. See the qemu documentation for available commands. Unfortunately the process of saving snapshots is not reliable. It may appear to work, but create a corrupted image.

	This is actually a full terminal interface. It is good for remote servers, where you don't want to run X (too unstable) but you want to be able to log in with ssh to administer the system. This also lets you run full-screen text mode applications such as aptitude and Midnight Commander. Curses is named for the full-screen terminal cursor, which can be anywhere in a 24 × 80 field.
