I haven't had any luck with qemu or virtual box. I don't run any sort of X environment over here, and they want it. I do use the bochs emulator. It has a "term" output mode, which works well with a text console. Bochs can run Linux, but it takes a long time to boot with the average live CD. This emulator is a good fit for people who are experimenting with small operating systems. Want to hack on your very own toy kernel? Bochs is definitely the ticket. User-mode Linux works beautifully. Grab a kernel source tree, and go through the usual compilation process, remembering to specify ARCH=um for all of the invocations of the make command. You'll need a filesystem to use with it. I have one that contains a minimal ArchLinux installation. User-mode Linux can use the virtual consoles of the host, so it is well-suited to Speakup. Another possibility for kernel hacking is that old stand-by, the serial console. -- Chris
