Paravirtualization is a type of virtualization where we will get instructions from the guest operating system running inside a virtual machine. This will directly communicate with the hypervisor. It will also provide an interface similar to software running natively on the host hardware. These instructions carried out by paravirtualization are incompatible with full virtualization.

It has a primary benefit: it can provide a speed of native code for time-critical functions. Apart from this, it also helps share hardware between multiple operating systems. It has been available from several vendors for the past few years. Let us look at some examples of virtual machine platforms supporting paravirtualization.

  • Oracle virtual machine hypervisor
  • VMware ESXi Hypervisor
  • Xen Open source hypervisor.

Para-virtualization for Automotive Systems

Paravirtualization can help embedded automotive systems share Access to peripherals. It will help switch Access between different operating systems that require the use of peripherals. This process includes an audio interface, touch interface, instrument display, and storage devices. It will support Access to peripherals in different ways.

Paravirtualization can also emulate hardware devices in a fully virtualized way. It means it can pass the Access directly By giving complete control of the virtual machine without knowing that our memory range has been reversed. However, in specific paravirtualization modes, the hypervisor will avoid the constraints of full virtualization.

Comparison between Paravirtualization and Cloud Computing

Paravirtualization is not directly opposite to cloud computing. Cloud computing services will provide both fully virtualized and para-virtualized environments. When cloud computing provides full virtualization, it will have a self-operating system and an application that will run as if it is hosted on the hardware being emulated. When working through this process, the guest operating system will be modified to run in the environment. This process mainly involved drivers supplied by the hypervisor vendor for each operating system support.
