Abstract
A processruns directly on a host operating system, until the processattempts an operation which can affect security of the host operating system(such as loading a kernel module or using system privileges). A guest operating systemis then provided running as a virtual machine session within a compartmentof the host operating systemand running of the processcontinues using the guest operating system. Operations of the processwhich can affect security of the host operating systemare instead performed on the guest operating system, giving greater security. The guest operating systemis only invoked selectively, leading to greater overall efficiency.
