How are you running qemu-iotests to make these tests fail? I tried to
reproduce, but they just pass for me:
$ tests/qemu-iotests/check -qcow2 -nocache 271 308 file-io-error
[...]
271 pass [11:20:50] [11:21:11] 21.1s (last: 20.4s)
308 pass [11:21:11] [11:21:14] 3.3s (last: 3.3s)
file-io-error pass [11:21:14] [11:21:14] 0.3s (last: 0.3s)
Passed all 3 iotests
$ tests/qemu-iotests/check -raw -nocache 271 308 file-io-error
271 not run [11:21:20] [11:21:21] ... not
suitable for this image format: raw
308 pass [11:21:21] [11:21:24] 3.8s (last: 2.8s)
file-io-error pass [11:21:24] [11:21:25] 0.3s (last: 0.3s)
Not run: 271
Passed all 2 iotests
