In server virtualization, a hypervisor provides an abstraction layer between the physical server hardware and the virtual machines (VMs) running on it.

The hypervisor is responsible for creating and managing virtual machines, including allocating resources such as CPU, memory, and storage to each VM. It enables multiple VMs to share the same physical resources while isolating them from each other, ensuring that a problem with one VM does not affect the others.

The hypervisor also provides a virtualized network interface for each VM, allowing them to communicate with each other and with the external network.

In summary, the hypervisor provides control and distribution of physical resources, which enables multiple virtual machines to run on a single physical server, maximizing the utilization of the hardware and reducing costs.
