Long description

The figure consists of a block containing two segments labeled from the bottom as Hardware and Type 1 hypervisor. The Type 1 hypervisor is labeled kernel mode. A smaller block labeled virtual machine is placed above the previous block. It consists of two segments labeled virtual kernel mode and virtual user mode. They have together labeled user mode. The virtual kernel mode contains a guest operating system that is pointed toward the type 1 hypervisor segment using an arrow labeled trap on privileged instruction. The virtual user mode consists of two open circles labeled user process.
