Re: Choice of VMs under i386 Stretch?

Why?  Often the question is not "which hardware should I pick to run
this VM" but "what kinds of technology should I use to run this software
on this hardware".  When "this hardware" is 32bit, and a VM is needed
between the two, then that's that.

Because the hardware features to permit efficient virtualization weren't available on i386-only CPUs. (And there's really no good reason to run a VM host [vs guest] in i386 mode if it can run in amd64 mode.)

That said I do not believe that any existing i386 32-bit-only hardware
that is still floating around even supports the virtual machine
extensions necessary to run a true VM host.

I haven't use qemu on my 32bit only i686 machines recently, but I see no
reason why it wouldn't work any more.

It's certainly possible to run software-only virtualization on an ancient CPU, but at that point (since it would clearly just be to scratch an itch, not for any practical reason) why ask for opinions instead of just playing around if playing around is the only goal?
