I'll really like CentOS/RHEL and will definitely stick with it. The point of my questions wasn't to complain or any like that, but just surprise because it seemed that the no 32 bit support didn't line up with my experience and just trying to make sure I understood everything.
Thanks, Dave
I suspect that with the notion of modern OSes normally needing at least 1G each even in a VM (often much more), the choice was to steer resources to the 64bit platform for virtulization because 32bit machines can't address nearly as much memory space, often a key factor for VMs.
given the amount of resources to maintain a platform that can't really support production workloads and most modern machines should be able to switch to 64bit OS pretty seamlessly, I suspect there was no justification to keep support for a 32bit version.
just my theory, not sure if it's of any help for you.
