Separate user is enough if you don't have world writable files in yoursystem. And of course user for such purpose shouldn't be in group(s) that have write access to your personal or system files. If you are unsure use VirtualBox ( http://virtualbox.org/ ) - it's free and open-source, or VMWare ( http://vmware.com/ ) - it's not free. On Debian (and probably Ubuntu) you can install VirtualBox by running "sudo apt-get install virtualbox". I do not recommend to use QEmu because it's less user friendly than VirtualBox (BTW, VirtualBox is based on QEmu).
VMWare workstation is not free, but you can get both VMWare server and VMWare player at no charge. It's available from the Canonical repositories as well: http://archive.canonical.com/ubuntu/pool/partner/v/vmware-server/
