KVM (Kernel Virtual Machine), the next generation of virtualized technologies, is a recent addition to Linux. KVM provides full virtualization that is currently considered superior to all other full virtualization technologies. It combines support for the latest hardware virtualization capabilities and the rapid feature development of the Linux kernel into a complete, highly functional, virtualization platform. KVM is the only virtualization technology that is fully incorporated into the Linux kernel. With Red Hat’s acquisition of Qumranet, the inventor of KVM, KVM is backed long term by the industry leading Linux distribution provider as well as the Linux community.
With a VPS Server, you will not have this problem since you have unlimited root access because your website is virtually isolated from other clients sharing the server. Other features that make a VPS Server a good choice include more available bandwidth and better data security. Although you are still sharing the server with other clients in a Virtual Private Server, at least you know that there is a portion dedicated only to your files, which means that you have your own operating system. A VPS is more secure because you do not share storage space with other clients. In a shared hosting service, once the security of one customer is compromised, the other clients sharing the same space may also be at risk.
