Binary translation in virtualization
WebThe cost of running the binary translator (vs. executing the translated code) is rarely significant; see again Figure 5. There are two reasons. First, the TC captures the working set and continued execution amortizes away translation costs for long-running work-loads. Second, the translator is quite fast because it does little anal- WebDec 14, 2024 · In the previous chapter, we have introduced some basic concepts about hypervisors and briefly touched upon the different techniques to virtualize x86: full virtualization using binary translation, paravirtualization and hardware virtualization.
