Which type of virtualization involves minimal interaction with the hypervisor?

Paravirtualization is characterized by its minimal interaction with the hypervisor, which is crucial for its functionality. In this virtualization type, the guest operating system is aware that it is running in a virtualized environment. It actively communicates with the hypervisor to request resources and services, which significantly reduces overhead and improves performance compared to full virtualization.

In paravirtualization, because the guest OS is modified to be aware of the hypervisor's presence, it can interact more efficiently, leading to optimizations that allow for better use of hardware resources. This design minimizes the amount of work the hypervisor must do, resulting in improved system performance and responsiveness.

On the other hand, full virtualization requires more interaction with the hypervisor as the guest operating systems run without modification, making requests for resources that the hypervisor must then translate. Container-based virtualization operates differently as it uses the host OS’s kernel and does not rely on hypervisors in the same way, focusing on isolating applications in user space. Therefore, paravirtualization stands out for its efficiency and reduced interaction with the hypervisor.
