Well, any SCSI controller should do, really. Or in fact, any block device that doesn't have removable media. I agree that there's no real reason to skip the test for s390. On the other hand, testing it on s390 doesn't really contribute anything to the test coverage as long as the suite is run for PC, too (because there is nothing machine dependent in the tested code path), so not running it would be tolerable. > Another approach would be to drop the -pci postfix, but I don't want to > introduce more usage of aliases. Maybe that would indeed be the easiest way.

So if we don't want to just skip this part of the test for non-pc like we already skip ther parts, we generally solve this kind of thing by just filtering out strings that differ between setups.

[Qemu-block] [PATCH 2/3] iotests: use -ccw on s390x for 051
The default cpu model on s390x does not provide zPCI, which is not yet wired up on tcg. Moreover, virtio-ccw is the standard on s390x, so use the -ccw instead of the -pci versions of virtio devices on s390x. Provide an output file for s390x.
