The [[wikipedia:QEMU|QEMU]] emulation environment, including the accelerators kqemu and kvm, lets you run a variety of software on your computer in a protected environment. This includes software that is incompatible with your operating system, and software for different processors. Another option is VMWare, commercial software with a no-cost runtime version.

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.
