In one embodiment, an interrupt acceptance control circuit is provided. The interrupt acceptance control circuit may monitor one or more guest interrupt controllers in a system in response to an IPI (or device interrupt) issued in a guest, to determine if each targeted vCPU in the guest has accepted the interrupt. If not, the interrupt acceptance control circuit may communicate the lack of acceptance to the VMM, in one embodiment. The VMM may attempt to schedule the vCPUs that have not accepted the interrupt, for example.
