does install Hyper-v as a server role on top of windows OS a bad idea in production environment? To me it's not real Virtualization and it's wasting system resource and windows OS might corrupt, need to patch very often, etc. And the time to rebuild it taking long time when disaster occurs. I have been using vmware esxi so far and I am very happy with it. But haven't tried the hyper option. Please share with me your experience and advices, thanks.
