![]() ![]() ![]() It allows one host computer to support multiple guest VMs by virtually sharing its resources such as memory and processing. Simply put, a hypervisor is software used to create and run virtual machines (VMs). It’s sometimes referred to as a virtual machine monitor (VMM). What is a hypervisor? Think of a hypervisor as a controller. Feel free to skip ahead to How Does a vCPU Work? or How Do You Calculate vCPU? Hypervisor They include hypervisor, socket, thread, physical core, and logical core. Next, let’s review a few more terms and definitions relating to virtual servers. As for a definition, a vCPU represents a portion or share of the underlying, physical CPU that is assigned to a particular virtual machine (VM). What is a vCPU?īefore we get started, what is a vCPU? vCPU is the abbreviation for virtual centralized processing unit. Quick hint, it’s not as easy as one core equals one vCPU. We’ll also look at the mathematics behind vCPUs and how to calculate the number of vCPUs and cores. In this article, we’ll examine what a vCPU is as well as the differences between vCPUs and traditional CPUs. What is a vCPU, or virtual processor, and how does it compare to a CPU? It’s the number one question that we receive from customers interested in purchasing cloud servers or bare metal. ![]()
