Abstract—With the diversification of hardware platforms, software compatibility issue has become increasingly prominent. Virtual machine with dynamic binary translation system is the key technology to solve this problem. This paper designs an operating system kernel level virtual machine with binary translation systems (KBT) which is embedded into kernel space as a kernel module. KBT reduces the number of virtual layers of the computer system, and introduces further optimization strategies using kernel mode advantages. Experiment results improves that, KBT’s efficiency is higher than existing binary translation systems about 25%. KBT also has some interfaces to support kernel module translation systems to run complex software, which are hard to run upon existing user space virtual machines.

Index Terms—Virtual machine, binary translation, operating system, kernel space, kernel module, virtual layer.
