Abstract: A system and method are disclosed for recreating graphics processing unit (GPU) state information associated with a migrated virtual machine (VM). A VM running on a first VM host coupled to a first graphics device, comprising a first GPU, is migrated to a second VM host coupled to a second graphics device, in turn comprising a second GPU. A context module coupled to the first GPU reads its GPU state information in its native GPU state representation format and then converts the GPU state information into an intermediary GPU state representation format. The GPU state information is conveyed in the intermediary GPU state representation format to the second VM host, where it is received by a context module coupled to the second GPU. The context module converts the GPU state information related to the first GPU from the intermediary GPU state representation format to the native GPU state representation format of the second GPU.

Abstract: A processing system may include a service operating system (OS) and a guest virtual machine (VM). The service OS may be a host OS or an OS in a service VM, for instance. The guest VM may have a physical address space. In one embodiment, a pseudo-device driver in the service OS causes an address within the physical address space of the guest VM to be mapped to an address within a virtual address space of a user level monitor (ULM) running on top of the service OS. When an operation that involves the physical address space of the guest VM (e.g., a direct memory access (DMA) operation requested by the guest VM, an interrupt triggered by the guest VM, etc.) is detected, the ULM may use its virtual address space to access the physical address space of the guest VM. Other embodiments are described and claimed.
