An interrupt information processing method, a virtual machine monitor, and an interrupt controller. The method includes receiving Q pieces of first interrupt information and obtaining a corresponding interrupt processing function from a specific register according to an interrupt number of each piece of first interrupt information. Calling the obtained interrupt processing function to obtain M pieces of second interrupt information. Obtaining an identifier of a virtual machine corresponding to the M pieces of second interrupt information. Writing the M pieces of second interrupt information and the identifier of the virtual machine into a virtual CPU interrupt interface such that after determining that the virtual machine is running, the virtual CPU interrupt interface sends the M pieces of second interrupt information to a processor corresponding to the virtual machine. Technical solutions provided in the embodiments of the present disclosure are used to improve interrupt information processing efficiency.
