Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
Both single-machine and cloud-based VPSes are managed using a software program called a hypervisor. The machine that runs the hypervisor is called the host machine and the individual virtual private servers are called guest machines or guest instances. The hypervisor can start and stop the virtual machines and allocates system resources, such as CPU, memory, and disk storage to each VPS.
VPS hosting, on the other hand, provides you with dedicated resources that you don’t need to share. Every virtual private server hosting plan makes sure that you get the highest control of your resources. Control your CPUs, Burst RAM, manage root access and use your preferred OS. The downside of VPS hosting is that, while we cover the back-end and server monitoring, maintaining it 24/7, we can provide limited help to your project concerning customer support. While all VPS hosting and control panel questions we will help with, programming, coding and other queries of similar nature won't be covered.

KVM’s popularity has been moving up on the list of virtual machine software’s due to its success with OpenStack. Marrying the 2 products together gives similar functionality as VMware vSphere, although there are some limitations with hosting Windows VMs, which are now taken care of by OpenStack’s ability to also support Hyper-V and ESXi.
