It's exactly the other way round. Virtualbox is a painless out of the box solution satisfying a lot of needs. Only if you have a very special need, consider to migrate to something less comfortable such as KVM.
You'll not only see performance gains and some more Linux-host-friendly design/features, but you'll also be guaranteed to have it always work with the newest kernel you have installed (provided you've rebooted after a kernel update), as KVM's kernel integration is part of mainline Linux.
And if virtualbox performs adequate you gain absolutely nothing from those performance gains, but you'll lose all the out of the box features virtualbox provides, such as file sharing without any effort.
