What 32-bit processor do you have?

There are a few types of VM's. Some would require more hardware support than others. One like qemu runs on almost any x86 system.

Your problem would be more of a memory issue I'd think. Even a PAE kernel can only support so much, I'd assume since you have a 32 bit host.

Umm. You mean by arch what? You have a 32-bit version of CentOs 6.4 installed or you have a CPU that has a 32bit architecture?

Anyways, you can virtualize 32-bit on 32-bit Linux installation and 32 AND 64 bit on 64-bit Linux installations. I dont even think the CPU matters (if you have a weak one with less features), just use qemu or something else that doesnt depend on hardware virtualization.
BUT if you have a CPU that has the Intel Vt-x/AMD-Vi virtualization extension (pretty much anything that has 64 bit capability nowadays), make sure you use it as it gives a significant performance boost.

Thanks for the list of web sites. I checked the first one and I can see lots of information I really need to read.

I'm afraid I may sound stupid but the Red Hat Enterprise v6 requires that you must have 64-bit to be able to install virtualization.

You must have 64 bit what (again)? 64-bit instructions capable CPU or 64-bit operating system architecture?

I am confused. I installed CentOS 6.3 and on of its System Tools is Virtual Machine Manager, and it says I need to install qemu-kvm, and qemu-kvm will not be installed unless I have glib-2.12, then I installed this one also, but still it is not finding it.

Yes. Please post info on one CPU from /proc/cpuinfo (including flags) and the output of uname -a
