OpenStack is sometimes called the Linux for clouds, and Red Hat, the dominant Linux distributor, seems to be all over that. The firm is now working to bring its Red Hat OpenStack distribution into the ever-crowding field of companies that want to peddle supported distributions of this cloud control freak. Red Hat Open Stack, or RHOS, is not ready for primetime, but a new RDO community – Red Hat is not saying what it stands for – is getting a Fedora-like early adopter community together running OpenStack on top of Red Hat's Enterprise Linux and KVM hypervisor.
