Latest industry news show that both Microsoft and Redhat had finally agreed to support each others in their virtualization technology to allow inter operation and support to each others. Beside SuSE Linux, we will later see the Redhat able to be run on Microsoft Hyper V. For consumer, is a good move absolutely for both Microsoft and Redhat users which allow their customer to standardize and consolidate their virtual environment more efficient. But if we compare both to VMware, I will say they are still far behind as we can see the capabilities from VMware to interop with any operating system base on x86 or x64 today.
