The principles of VAX Hardware Virtualization
In order to make the correct decisions regarding how to apply VAX Hardware Virtualization or Emulation, it is important to make a distinction between the VAX hardware that is virtualized or emulated and the (non-VAX) hardware from the (non-VAX) hardware host platform that carries the VAX Virtualization Software.

CHARON-VAX virtualizes various VAX architectures and meets or exceeds the performance level of these VAX systems when run on the recommended hardware platform. Our VAX emulator product is currently available in contains the following variants:

Host platform
The Virtualization Software presents standard VAX devices to the VAX operating system, allowing the OS to function as though it were still running on a VAX computer. For example, virtual disk container files in a directory or device files in /dev directory of the host Linux platform are presented by the Virtualization Software to the VAX OS as emulated SCSI disks attached to a SCSI adapter.
