Laptops and hardware virtualization

[Jerry Feldman]

A while back I tried to set up KVM on my system and it would would not
let me do it. I could configure and virtualize with QEMU, but not KVM. I
would double check on Xen as AFAIK, it has required hardware
virtualization for a number of years even with Xen-aware guests.
