Why is it impractical to use a virtual machine for a hard real-time system?
What will be an ideal response?
Hard real-time systems must perform certain tasks immediately. This requires that the system has immediate access to hardware when those tasks must be performed. Since a virtual machine is just an extra software layer between the application and the hardware, using a virtual machine would be inefficient.
