OK, so I've been playing around with Linux on a virtual machine, but I
have a question: Has anybody put together a Linux distro that is
especially designed to be run on a virtual machine?
I mean, if I'm running on a virtual machine, I do *not* require
functionality such as software RAID, USB support, temparature
monitoring, Bluetooth support, Firewire support, hardware diagnostics,
printing and scanning, CD-burning, or *cough* virtualisation. (What sick
weirdo runs a VM inside a VM??)

No, but you could always try a minimalist distro, like damnsmall Linux
or Puppy Linux:

Are you willing to learn the ways of the command-line or user-level GUI?

A minimalist linux distro (without fancy graphical user interfaces, etc)
can be made so small that you can put it into a bootable floppy, and boot
from it.
In fact, some people do that with hardware firewalls which do not have
a hard drive (on purpose). Given that the floppy is write-protected, it's
impossible for a hacker to permanently hack the system (a simple reboot
is enough to kick any possible hacker off the system).
(OTOH nowadays booting from a CD has mostly obsoleted booting from a
floppy. And the CD can have luxuries like X and other crap like that. :P )

Actually, I possess such a thing. ;-)
Obviously, it's a single-purpose tool though. It's never going to
replace a normal Linux distro.
I was just wondering if anybody has ever build a distro taylored to
removing all the parts that aren't necessary for running in a virtual
machine (e.g., support for various hardware that a VM won't have).
I guess the ultimate would probably be to design a special VM and a
special OS to run inside it... but by that point you've probably lost
the advantages of having a VM.

Generally, you could do this, but hardware support (for example) is done
using modules, so you could just remove the modules once the base OS is
installed.
That said, I've been alpha testing SUSE Studio (http://susestudio.com),
right now it uses a stock kernel, so the smallest system I've been able
to build is still about 100 MB in size (74 MB is the kernel); the way it
works, though, you could pretty easily clear out the cruft that's not
needed for a VMware system by running your pre-built system in the test
drive (which is a cool feature I haven't seen anywhere else - you don't
have to download the system to test it, you test it on a server farm
hosted by the site, with some significant networking restrictions) and
can save off a list of changed files that can then be imported into the
appliance.
Then you can generate a disk image, ISO for a LiveCD/LiveDVD, or a VMware
virtual machine.
And I've just answered one of my own questions about customizing the
system; we've got a CD image we use with a thin client for our practical
exams that's built on DSL and is only something like a 13 MB download,
great for remote parts of the world where bandwidth is a challenge.
I've been trying to duplicate what our ISO does with Studio, but can't
shrink it enough. Now I know how. ;-)

This is how I heard about QEMU, yes. ;-)
Of course, you can't actually "do" anything with DSL, because it doesn't
come with any software. So I'd like something with more functionality
than DSL, but I don't need hardware detection (because there's nothing
to detect).
