Abstract
By loading deprivileged drivers, such as third party supplied drivers, into a virtual machine under control of a virtual machine monitor, a kernel may be protected from faults that arise on those drivers. When a fault is detected, the system may transition from a guest mode, wherein the third party drivers operate through the virtual machine monitor, to a monitor mode, wherein the monitor takes control and provides appropriate correction if possible. In some cases, the virtual machine monitor may simply destroy and restart the virtual machine. In such cases, it may be possible to overcome the faults without crashing the entire operating system.
