As I wrote in the previous mail, emulators are one possible implementation of virtualization. If you look at virtualization, you basically have 3 ingredients: a host system, a guest system, and a layer coordinating the access from the guest system(s) to the real HW of the host.

- If the CPUs of host and guest are not the same, you need an emulator (RISC-5 on Intel)
- If the CPUs of host and guest are the same but the OSes differ you need a hypervisor like VMWare (Linux on Windows)
- If CPU and OS of host and guest are identical you can use containers administered eg by Docker (Linux on Linux)
