Claim:
1. A method of migrating interrupts from a source input/output (‘I/O’) adapter of a source computing system to a destination I/O adapter of a destination computing system, the method comprising: collecting, by a source hypervisor of the source computing system, interrupt mapping information, wherein the source hypervisor supports operation of a logical partition executing on the source computing system and the logical partition is configured to receive interrupts from the source I/O adapter; configuring, by a destination hypervisor of the destination computing system, the destination computing system with the interrupt mapping information collected by the source hypervisor; placing, by the 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; and restarting the logical partition on the destination computing system, including recovering, by the logical partition, from the error state.
