People who know what both of them are (hello) still won't know which one the headline is talking about.

The circuit one is definitely older, probably has more users, and is just as relevant in this forum.

You mean ‘virtualization’ here, I guess.

Nope. I work with virtualization on Linux every day, and have done so for many years (and many varieties of virtualization). I didn't recognize it by the name, and I don't remember hearing about it before.

Yes, a circuit simulator.
