Oracleâ€™s latest cloning effort
A while back, Oracle cloned Red Hat Enterprise Linux as Unbreakable Linux (now 'Oracle Enterprise Linux'). It offered nothing new over REHL (or for that matter, CentOS), and the only difference was the support price. Needless to say, Oracle Enterprise Linux hasn't been a stellar success.
So what's new? Another clone of a popular product. In this case, a virtualization hypervisor based on (surprise, surprise) Xen.
Apparently they're competing on cost again. I'm not sure, but I think I can predict where this is going to end up...
