Claim:
1. A method of migrating interrupts from a source input/output (‘I/O’) adapter of a computing system to a destination I/O adapter of the computing system, the method comprising: collecting, by a hypervisor of the computing system, interrupt mapping information, wherein 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.
