    "patent_abstract": "A computing device can detect an interrupt associated with a virtual machine. Based on detecting the interrupt, the computing device can determine whether the virtual machine is in an idle state. Based on determining that the virtual machine is in the idle state, the computing device can delay the interrupt by storing the interrupt in an interrupt register for a period of time and preventing the interrupt from being transmitted to the virtual machine during the period of time. After storing the interrupt in the interrupt register, the computing device can determine that the virtual machine is in an awake state. In response to determining that the virtual machine is in the awake state, the computing device can transmit the interrupt from the interrupt register to the virtual machine.",
    "precision_class": "structural",
    "invention_explanation": "A virtualization system that holds an interrupt while a virtual machine is idle, then delivers it later instead of waking the machine immediately.",
