We have several big clusters built on mixed virtual and bare metal. I would prefer our system engineer to manually build on virtualbox before even touching hyper-v (which we clearly don't!). For some political reasons our IT forced us to test to build a solution on hyper-v (cost saving on some non critical infrastructure proposed by some very non-tecnical people), I still have nightmares. I am not even the person who had to do it in practice.

It is long to explain it here, just give it a try. Windows server and all releted solutions are simply bad for real workloads. Who use it on server is just a company who doesn't need to be productive on the IT side. Their core business is not tech related and they don't care other than getting cheap sys admins

Well, I mean, that. It's very capable but Microsoft gimps it by bundling it with windows server. The fact you have to use RDP to administer it is itself a non-starter.
