COMPUTER AND INTERRUPT CONTROL METHOD

摘要

In a computer in which a plurality of virtual machines (VMs) is operated, the plurality of VMs is managed in such a manner that the VMs are separated into a priority group constituted of VMs in a priority mode and a non-priority group constituted of VMs in a non-priority mode. A virtualization management unit sets a physical computation device except a physical computation device assigned to the VM in the priority mode as a physical computation device for receiving a hardware interrupt issued from a physical interrupt device assigned to a virtual interrupt device held by the VM in the priority mode. The virtualization management unit operated by the physical computation device that has received the hardware interrupt specifies a physical computation device assigned to the VM in the priority mode which is a transfer destination of the hardware interrupt, and transfers the hardware interrupt to the specified physical computation device. The physical computation device that has received the transferred hardware interrupt specifies the VM as a target of the hardware interrupt, and issues a virtual interrupt with respect to a virtual computation device held by the VM specified on the basis of the hardware interrupt.
