Abstract
A system and method for executing a transaction in a transactional memory system is disclosed. The system includes a processor of a plurality of processors coupled to shared memory, wherein the processor is configured to execute a section of code, including a plurality of memory access operations to the shared memory, as an atomic transaction relative to the execution of the plurality of processors. According to embodiments, the processor is configured to determine whether the memory access operations include any of a set of disallowed instructions, wherein the set includes one or more instructions that operate differently in a virtualized computing environment than in a native computing environment. If any of the memory access operations are ones of the disallowed instructions, then the processor aborts the transaction.
