"WebOur software VMM uses a translator with these properties: Binary. Input is binary x86 code, not source code. Dynamic. Translation happens at runtime, interleaved with ex-ecution of the generated code. On demand. Code is translated only when it is about to execute. This laziness side-steps the problem of telling code and data apart. System level. " - Dynamic binary translation virtualization
