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 Kevin
