VAX Hardware Virtualization allows users of HP VAX computers to move application software and user data to a non-VAX platform without having to make changes to software and data. VAX Hardware Virtualization is a software solution that replaces VAX hardware.
This approach is best understood when the VAX Hardware Virtualization Software is viewed as a special interface between the old VAX software and a new hardware platform. Basically, the CHARON software presents a VAX hardware interface to the original VAX software, so that the existing software cannot detect a difference. This means no changes have to be made to the existing software. User programs and data can be copied to a new modern industry standard server (64-bit or 32-bit Intel or AMD) and continue to run for many more years.
