What is a virtual CPU (vCPU)? – Hyve Managed Hosting


Hi, my name is Chris. I’m one of the system engineers here at Hyve Managed Hosting and today, we’re going to be talking about vCPUs. So what is a vCPU? This is a virtual central processing unit which runs on virtualisation software. One or more vCPUs are assigned to every virtual machine within a cloud environment. The VM’s operating system will see each vCPU as a single physical core. Now the way this works is by using the physical CPU in a host server as its own virtual processor. This allows multiple VMs to be hosted on a single CPU. The number of vCPUs that can be assigned to a virtual machine is dependent on a few factors: the number of physical CPUs in the host, the number of cores per CPU, and if the CPUs are hyperthreaded. For more information on vCPUs, please don’t hesitate to leave a comment below or get in contact with us directly. Thank you for watching the video and we look forward to seeing you in the next one.
