Abstract

A system and method including, in some embodiments, receiving a request for a graphics memory address for an input/output (I/O) device assigned to a virtual machine in a system that supports virtualization, and installing, in a graphics memory translation table, a physical guest graphics memory address to host physical memory address translation.
