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..).
