Types of hardware virtualisation

Types of hardware virtualisation

1. Full virtualisation

   • run isolated Unchanged OS
     • More compatible
       • More portable
         • Less secure
           • ACTS AS INDEPENDENT OS AND GIVE HARDWARE COMMANDS
   • Operations are directly executed

2. Paravirtualisation

   • partial isolation
     • operation done using hypercalls
       • compatibility issues
         • faster
           • more secure
             • doesn't give hardware commands
               • issue commands to host os

3. Hardware Assisted

   • Uses special hardwares to do virtualisation
     • allow guest to execute directly on hardware
       • can be said intermediate between para and full virtualisation
         • doesn't need gues to be completely paravirtualised
