Thanks - that's a huge clue, not turned up in my previous searching.

Interesting -- that's not what the man page says, so I guess we should
fix the man page.

reading, it seems "Unrestricted Guest" is sort of linked to Extended
Page Tables.

What is the 'cpuctl identify' codepoint for unrestricted guest?

What is the approximate date by which (non-celeron/reduced-power/etc.)
Intel CPUs generally support nvmm?

(It turns out the computer I thought was more 2014ish has a CPU from 1Q
2010:

That cpu claims EPT, but cpuctl doesn't show it.
