as i'm reviewing the courseware for the rhel (centos) course i'm teaching next week, i'm going to ask the occasional question, possibly technical, possibly more policy.
first one involves the choice for virtualization. the course has a short section involving virt using xen but everything i've read suggests that red hat is concentrating on kvm for virt. thoughts on that? i have the freedom to replace the xen section with one covering kvm instead.
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..).
