Long description

The figure shows a block containing two segments. The bottom segment is labeled hardware. The top segment is divided into two parts labeled type 1 hypervisor and microkernel using a dashed line. Two smaller blocks are placed on the two sides of the top segment. The left block contains two segments, the first segment is labeled unmodified windows which point toward type 1 hypervisor using an arrow labeled trap due to sensitive instruction and the second segment consists of two open circles labeled true virtualization. The right block also contains two segments. The first segment is labeled modified Linux which points toward the microkernel using an arrow labeled trap due to hypervisor call and the second segment consists of two open circles labeled paravirtualization.
