Fortunately, RH will support Xen at least through RHEL 5's EOL.  I'm
sure the company I work at is not alone in having a lot of older but
still good hardware around that is great for Xen even if it's not cared
about by KVM developers so much :)

(I'm thinking Dell PE 2850's, etc.. perfectly good servers that these
is no reason to toss)

OpenVZ might be a good option for you as well depending on your use
case.
