When you're building a distributable virtual appliance you want your OS
to be start as small as possible. If you use Ubuntu Server you've got a
lot more unnecessary bloat to cut down on. Virtual machines tend to run
specific tasks, rather than be multi-function servers. Resources in a VM
are also more precious than on a host OS because they are rationed by
the host software.
