I've gone all the way down this path with Xen but ended at a road block. VMware Workstation says it can run in a Xen VM and halts. If you grab VMware Server it lets you go, but during an install of CentOS early on, it freezes. I'm not sure #2 is possible with KVM. Can someone comment if they are doing this reliably?
