Kernel-based Virtual Machine (KVM) is an open-source virtualization technology built directly into Linux. This provides each VPS with all typical services of the physical system that the VPS is hosted on, including virtual BIOS (basic input/output system) and virtual hardware, such as processor, memory, storage, network cards, etc. As a result, every VM completely simulates a physical machine. This effectively means your VPS thinks it’s a full-blown dedicated server, so you administer it in the same way as you would a dedicated machine. However, with a VPS you don’t need to worry about the headache of maintaining a physical dedicated server, we take care of that.
