There are some implementations of a virtual machine engine that rely on the techniques of emulation. For example, they emulate the x86/x64 architecture by adding a translation layer at the guest OS level, which enables them to execute on different platform architectures like the PowerPC, as well as x86/x64. However, this additional layer slows down the virtual machine quite significantly.
Modern virtualization techniques implement the isolation and segregation of the virtual machine within system memory. With support from modern hardware that provides special instruction-set for virtualization, the virtual machine engine passes on the execution of the guest virtual machine directly to the native hardware. ...
