This only affects anyone that wants to spin up VirtualBox VM's on Linux hosts. I'm not an expert in this field, but my best TL;DR is that VirtualBox and other VMM's (virtual machine monitor) used to ship with their own hypervisors (the thing that let's you run virtual machines). However, now Linux has its own hypervisor/framework (KVM) and now VirtualBox can use KVM to do all the functionalities their own hypervisor used to do. Someone please correct me if I'm wrong
