XS Japan 2008 BitVisor English

BitVisor is a security-focused virtual machine monitor (VMM) developed in Japan with the goals of encrypting storage and networks and using smart cards for authentication and key management. It uses a para-virtualization approach where most device I/O is passed through directly to the guest operating system, unlike Xen which uses full virtualization and device emulation. This makes BitVisor's VMM smaller and lower overhead than Xen. Experimental results showed BitVisor running Windows and Linux guests with encryption of storage and networking.
