The present invention provides a virtual interrupt management method and apparatus in a distributed virtual system. The method comprises: a virtual BIOS module establishing in an ACPI table a connection relationship between global virtual interrupt pins and interrupt pins of virtual PCI devices, any one of the global virtual interrupt pins corresponding to an interrupt pin of one or more virtual PCI devices belonging to the same physical node; an operating system of a virtual machine acquiring the ACPI table, and running, according to the ACPI table, an instruction of setting a target vCPU for the global virtual interrupt pins in the ACPI table; a distributed virtual machine monitor that intercepts the instruction determining, according to distributed interrupt pin information, a physical node where a local virtual interrupt pin corresponding to the global virtual interrupt pin is located, and saving a relationship between the local virtual interrupt pin and the target vCPU according to the instruction, the target vCPU being used for processing an interrupt on the local virtual interrupt pin. |
