I'm involved in a selection and acquisition project for a virtualization environment for a medium sized university in Peru. The choices for hardware are rather obvious. The question is what hypervisor to choose. The university has a usercommunity of 2000 people. Currently some 20 to 30 servers. We want to implement a virtualization environment that has migration or live migration capabilities.
My question is if anyone has real life experience with the 3 big hypervisors that there are at the moment being VMWare (leader and most expensive) vs Hyper-V vs XenServer.
I'm not looking for performance metrics since they don't mean too much to me. I'm looking for comparison in the area of features, reliability, robustness, ease of management, etc
What would you say?
