Abstract
In an embodiment, a system comprises a memory system and a guest interrupt manager. The guest interrupt manager is configured to receive an interrupt message corresponding to an interrupt that is targeted at a guest executable on the system. The guest interrupt manager is configured to record the interrupt in a data structure in the memory system to ensure that the interrupt is delivered to the guest even if the guest is not active in the system at a time that the interrupt message is received.
