Hypervisor-based systems such as Xen use less resources than full CPU  
emulation such as KVM, Xen and Parallels. If you're specifically  
interested in building lots of virtualised Linux boxes, I'd recommend  
Xen.

If you want even lower resource usage, look at linux-vserver. It's  
orthogonal to Xen so you can even run it within a Xen domain - both  
Dom0 and DomU - if you like. Linux-vserver runs on an even wider range  
of architectures to Xen.
