Emulation and virtualization are two very different concepts.
Every OS you virtualize must be supported by the base processor in the hardware. That is not so in an emulation, where another architecture can be supported.
See the differences between qemu and virtualbox.
- m_mueller 8y agoThis is in contradiction to eschaton, and I agree with GP in this regard: pass-thru of CPU instructions to host hardware is just an optimization, not a defining feature of virtualization. There were VM hosts before processors supported this, and back then I think that virtualization == emulation.
