The state of the thread interrupt management registers needs to be collected for migration. These registers are cached under the 'xive_saved_state.w01' field of the VCPU when the VPCU context is pulled from the HW thread. An OPAL call retrieves the backup of the IPB register in the underlying XIVE NVT structure and merges it in the KVM state.
