I'm running both Xen and KVM. If you're using the virt-* tools then RedHat does a pretty decent job of hiding the underlying virtualization engine. My virt-install script ran pretty much unchanged from Xen to KVM. If you're teaching a troubleshooting course, I think you need to cover both technologies as I do see a lot of Xen machines out there. Otherwise I'd concentrate on KVM and maybe give a few minutes on the differences (how disks are referenced, setting up bridging adapter, etc..).
