In my lab, I am in the process of moving off of Vmware/ESXi and onto RHEV (Red Hat Enterprise Virtualization). So far the learning curve has not been that bad.... Installing and configuring RHEV-M was just as simple as installing a few packages on top of RHEL 6. I had an unused desktop that was more than up for the task. For RHEV-H... Well I had just finished building out a server for it. Once my initial hardware was up and running it was time to start moving virtual machines out of Vsphere.
