Abstract: “System virtualization techniques are broadly used to distribute computing power, to boot different operating systems virtually on top of a host OS, to enable security features like encapsulation or to provide redundancy and migration concepts. Virtual machines (VMs) targeting different Instruction Set Architectures (ISA) are usually implement by efficient emulation or binary translation techniques. This paper uses reconfigurable hardware to support (guest) operating system virtualization and not virtualization of hw-accelerators inside an operating system. The main idea of this paper is to replace emulation / binary translation by (re)configuration. Instead of emulating a processor-ISA on a CPU with another ISA, the required guest-processor will be configured into an FPGA and booted with a guest operating System (OS) as requested by a VM manager. This approach allows to overcome limitations of conventional system virtualization approaches, like the Popek and Goldberg theorem and provid”
