Lots of noise this morning about problems at VMWare. Due to power and cooling limitations at data centers, virtualization will continue to grow. But with EMC exerting control over VMware, IT folks are starting to look at open source alternatives. Red Hat bought Qumranet and has its own free V solution in XEN. Sun released its Hypervisor to open source. Even MS is adding VM to its next version of server. Virtualized Machine will become utility soon.
