Hypervisor

What is Hypervisor

In simple words, a hypervisor is computer software, firmware or hardware that creates and runs virtual machines. 


  • A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. 
  • The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. 
  • Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine.  

The hypervisor is classified into two types:
  1. Baremetal - Hypervisor lying on the hardware
  2. Hosted - Hypervisor lying on the Operating system
