....environments [21] Within a constrained VM, legacy operating systems and applications are executed unmodified and are easily upgraded and replaced even within the context of rapidly evolving software product lifecycles. In the past, some virtual machine monitors, such as the SDC KVM 370 [11, 9, 33, 10] and the DEC VAX SVS [17] have been used to separate mandatory security classes. A secure VMM for the Intel Pentium 1 processor architecture would be very desirable because a single machine could be used to implement critical security policies while also running popular Win32 operating systems ....

.... suggested that the redundant security mechanisms found in the VMM and the OS executing in one of its virtual machines enhanced security [21] Penetration experiments indicated that redundant weak implementations are insufficient to secure a system [5, 11] KVM 370was an early secure Type I VMM [11, 33, 9]. Called a security retrofit, two approaches to the work were examined: 1) hardening of the existing VM 370 control program (CP) to repair identified penetration vulnerabilities and (2) a redesign of the VM 370 CP to place all security relevant functionality within a formally verified ....
