Live migration of virtual machines from/to host computers with graphics processors

An apparatus for computing, comprising:

• one or more general purpose processors;
• a graphics processing unit;
• system memory coupled with the one or more general purpose processors and the graphics processing unit;
• and
• a virtual machine monitor to manage virtual machines hosted by the one or more general purpose processors, wherein the virtual machine monitor includes:
• a memory manager to manage accesses of the system memory by instructions of applications of the virtual machines, executed by the one or more general purpose processors;
• and
• a graphics command parser to analyze graphics commands issued to the graphics processing unit by the applications to determine whether the graphics commands are supported by the graphics processing unit.

An apparatus for computing, comprising:

• one or more general purpose processors;
• a graphics processing unit;
• system memory coupled with the one or more general purpose processors and the graphics processing unit;
• a virtual machine monitor to manage virtual machines hosted by the one or more general purpose processors;
• and
• a graphics proxy library to be instantiated in at least a first of the virtual machines, wherein the graphics proxy library is to maintain a context of a graphics application programming interface that abstracts the graphics processing unit for the first virtual machine.

A method for computing, comprising:

• analyzing, by a graphics command parser of a computing system, graphics commands issued to a graphics processing unit of the computing system by applications of virtual machines of the computing system;
• detecting, by the graphics command parser, writes to system memory of the computing system, caused by the graphics commands;
• and
• on detection of writes to system memory, augmenting, by the graphics command parser, modified memory pages tracking by a memory manager of a virtual machine monitor of the computing system.
