I've made some minor edits to clarify a bunch of bits, and a link to the Kernel doc about Intel nVMX. (Hope that looks fine.)
I'm sure they it does, but just so you know I currently don't see any edits from you on the Nested Guests page. Are you sure you saved/published your changes?
Thanks for catching that. _Now_ it's updated. https://www.linux-kvm.org/page/Nested_Guests (I also didn't have permissions to add external links; had to get that sorted out with the admin.)
You wrote: "L2...which does no further virtualization". Not quite true — "under right circumstances" (read: sufficiently huge machine with tons of RAM), L2 _can_ in turn L3. :-)
Insert "normally" between "which" and "does", then. :)

Last time I checked (this morning), Rich W.M. Jones had 4 levels of nesting tested with the 'supernested' program[1] he wrote. (Related aside: This program is packaged it as part of 2016 QEMU Advent Calendar[2] -- if you want to play around on a powerful test machine with tons of free memory.)

Interesting, thanks for the pointer!
Cheers, Florian
