At a potential performance penalty and significant extra attack surface (you now have to worry about your hypervisor’s attack surface and your actual OS’ attack surface, where as on bare metal you only have a single OS to worry about). Not to downplay the advantages of virtualisation, but if all you needed was a bare metal server then running a hypervisor adds one extra thing that can go wrong that you didn’t ask for.



Most (if not all) home lab users will be using virtualisation to spin up multiple VMs.
