coordination between the guest operating system and bare hardware, and some protected instructions must be captured by hypervisor (hypervisor). Full virtualization runs faster than hardware simulations, but is less performance than bare metal. Semi-virtualized (Para virtualization)Para-virtualization is another technology similar to full virtualization, which uses hypervisor to share access to the underlying hardware, but its guest operating system integrates virtualization-related code.
