Unless a channel device is used for some critical I/O, Linux is able to recover from channel path changes. Without these changes, KVM guest will not successfully handle situations that Linux would otherwise recover from whem running in LPAR or as a z/VM guest, e.g. channel path changes caused by the FICON fabric, or simply offlining and subsequently onlining. This feature is critical to use vfio-ccw in production.
