Long description

The figure shows two sets of blocks labeled normal context switch and VMware world switch. The normal context switch contains two blocks process A and Process B. The block under process A is divided into two parts labeled A (user space) and Kernel space. The block as a whole is labeled linear address space. The block under process B is divided into two parts labeled B (user space) and Kernel space.

The VMware world switch contains two blocks host O S context and V M M context. The block under the host O S context is divided into two parts labeled V M X (user space) and kernel address space (host O S). The block under the V M M context is divided into two parts labeled virtual machine and V M M. Here the virtual machine occupies a larger part and V M M occupies a smaller part.
