A systems administrator is deploying several virtual servers on a new rack-mounted host. To achieve the highest possible performance and remove the overhead of a host operating system, the administrator wants the virtualization layer to run directly on the server hardware. Which of the following technologies best meets this requirement?
A Type 1 hypervisor (bare-metal hypervisor) installs directly on the physical hardware, giving virtual machines direct access to resources and eliminating the performance overhead of a host OS. Type 2 hypervisors run on top of an existing operating system, so they do not meet the performance requirement. A container engine relies on the host OS kernel, and a VDI client simply accesses a remote desktop, so neither provides the desired virtualization layer.
