WebDynamic binary translation (DBT) is a core technology to many important applications such as system virtualization, dynamic binary instrumentation, and security. However, there are several factors that often impede its performance: 1) emulation overhead before translation; 2) translation and optimization overhead; and 3) translated code quality. WebDynamic binary translation •Idea: intercept privileged instructions by changing the binary •Cannot patch the guest kernel directly (would be visible to guests) •Solution: make a copy, change it, and execute it from there –Use a cache to improve the performance
