Yes, it is, true, but are there any 32-bit only x86 CPUs which have
Intel VT or AMD-V?

To be honest, I have never even looked at it - I do not own, nor ever
have owned, a PC with a virtualisation-capable CPU. I was under the
impression that it did not have a GUI or anything, nor did it support
features like guest additions, shared mouse pointers or clipboards,
disk or file sharing between guest and host etc.

Given that there are free solutions that do all this, it would seem to
me to be something aimed at places where such functionality is not
important. That is, servers, mainly. That is the only place and role
where I have heard of people running it, as far as I can remember.
