摘要： A system and method dynamically assign interrupts to a virtual machine from an input/output (I/O) adapter based on I/O metrics of the I/O adapter. An interrupt manager monitors I/O adapter traffic flow metrics such as latency of data transfers, usage levels, and transfers per unit of time. The interrupt manager determines when a traffic flow metric for a virtual machine meets a predetermined performance threshold and updates virtual interrupt assignments in a logical interrupt table to improve performance of the system.

摘要： Live partition mobility in a computing environment that includes a source system and a target system may be carried out by: pausing a logical partition on the source system, wherein the logical partition is mapped to an I/O adapter of the source system; copying, to the target system, configuration information describing the mapping of the logical partition to the I/O adapter; copying, to the target system, the logical partition of the source system; placing an I/O adapter of the target system into an error state; mapping, in dependence upon the configuration information, the logical partition of the target system to the I/O adapter of the target system; placing the I/O adapter of the target system into an error recovery state; and resuming the logical partition on the target system.

摘要： Migrating interrupts from a source I/O adapter of a computing system to a destination I/O adapter of the computing system, includes: collecting, by a hypervisor of the computing system, interrupt mapping information, where the hypervisor supports operation of a logical partition executing and the logical partition is configured to receive interrupts from the source I/O adapter; configuring, by the hypervisor, the destination I/O adapter with the interrupt mapping information collected by the hypervisor; placing, by the hypervisor, the destination I/O adapter and the source I/O in an error state; deconfiguring the source I/O adapter from the logical partition; and enabling the logical partition and destination I/O adapter to recover from the error state.

摘要： Apparatuses, methods, program products, and systems are presented for interrupt virtualization. An apparatus includes an adapter module that detects a switch from a first physical input/output (“I/O”) adapter associated with a logical partition to a second physical I/O adapter associated with the logical partition. The apparatus includes an interrupt module that updates one or more I/O interrupt management structures for the logical partition so that the logical partition receives I/O interrupt information from the second physical I/O adapter and not the first physical I/O adapter without the logical partition being aware of the switch to the second I/O adapter. The apparatus includes an abstraction module that updates physical device information at a hypervisor for the logical partition to reflect the switch to the second physical I/O device.

摘要： Managing a pool of virtual functions including generating a virtual function pool comprising a plurality of virtual functions for at least one single root input/output virtualization (SR-IOV) adapter; creating a control path from a client virtual network interface controller (VNIC) driver in a first client partition to a target network using an active virtual function; receiving a failure alert indicating that the control path from the client VNIC driver in the first client partition to the target network using the active virtual function has failed; selecting, from the virtual function pool, a backup virtual function for the first client partition based on the failure alert; and recreating the control path from the client VNIC driver in the first client partition to the target network using the backup virtual function.

摘要： Migrating memory MMIO from a source I/O adapter of a source computing system to a destination I/O adapter of a destination computing system, includes: collecting, by a source hypervisor of the source computing system, MMIO mapping information, where the source hypervisor supports a logical partition on the source computing system and the logical partition is configured for MMIO operations with the source I/O adapter through an MMU; placing, by a destination hypervisor of the destination computing system, the destination I/O adapter in an error state; migrating the logical partition from the source computing system to the destination computing system; configuring, by the destination hypervisor of the destination computing system, the destination computing system for MMIO with the LPAR utilizing the MMIO mapping information collected by the source hypervisor; and restarting the logical partition on the destination computing system, including recovering, by the logical partition, from the error state.
