You can use Qemu to boot a CD ISO image you downloaded before you even burn it. This could be useful for just checking it out before you decide to spend a CD for burning it or to take screenshots you otherwise wouldn't be able to from the real bootup.

qemu -cdrom cdimage.iso

You can even install a CD image on a special virtual disk you can create on qemu. This disk is actually not a disk, of course, but a disk image which contains free space that can be used within qemu emulation.

I'm wondering if Gentoo desktop installations are a good thing for the environment. When I don't need my computer I tend to switch it off, since it'll only take some minute to start it up again if I want it.
