Comparison of virtual machines
In the table comparison of the main characteristics of virtual machines is included below. Remember that all virtual machines mentioned here are hypervisors (emulators of the hardware). Any of them is not virtualization of applications, such as Java Virtual Machine or Parrot Virtual Machine.
