In the event of a hardware error, the vmkernel can 'catch' a Machine Check Exception.

Processor state is buffered in a way that allows precise core retry for almost all hardware errors.

Industry executives and technical experts said they were less concerned about the actual hardware error than by the way Intel was responding.
