Yes, you are right. While last time I tried to run a 32bit guest, it took me a
lot of time to setup. If my understanding is correct, to run on a 32bit
machine, we not only need the kernel but a whole 32bit system. This means I
need to re-install a 32bit system. And I found many distro doesn't support
32bit system any more.

Do you have a better way to setup the environment?
