Alright, so let's say your server has 2 quad core xeon CPUs and 16GB RAM. You sell "6 cores" to one person, and "6 cores" yet again to another. You only have 8 cores there alone, so how does that work? Moreso, how do you even profit from this?
Also, your KVM servers are unmanaged by default. You have to pay an extra $100/month for them to be managed.
