What’s the difference between a LXC and a KVM VPS?

A key difference between an LXC and a KVM VPS is that LXC is a container-based virtualization technology, meaning it shares the host machine’s kernel, while KVM is a full hardware virtualization technology where each virtual machine runs its own separate kernel, providing greater isolation and flexibility to run different operating systems on a single server; essentially, LXC is lighter and faster for Linux-only environments, while KVM offers more robust isolation and wider OS compatibility.
