Apparently doing things is hard because neither [CPU-Z nor Intel's site report whether or not this is supported](https://superuser.com/questions/286937/what-features-should-i-look-for-in-a-laptop-for-virtualization-heavy-workloads/286941#286941), which seems strange to me.

So.. if I'm in a position where I can't just go to the laptop and install a virtualization package to check (e.g. the best I can do is run something from a USB key), how can I tell if a CPU has this feature?
