This breaks virt-alignment-scan. Not sure why yet.
It happens because adding -s changes the exit code of parted, so a previously hidden error is exposed, and that in turn breaks the part-list command when used on a blank disk. $ parted -m -s -- tests/guests/blank-disk.img unit b print Error: /home/rjones/d/libguestfs/tests/guests/blank-disk.img: unrecognised disk label BYT; /home/rjones/d/libguestfs/tests/guests/blank-disk.img:104857600B:file:512:512:unknown::; $ echo $? 1 $ parted -m -- tests/guests/blank-disk.img unit b print WARNING: You are not superuser. Watch out for permissions. Error: /home/rjones/d/libguestfs/tests/guests/blank-disk.img: unrecognised disk label BYT; /home/rjones/d/libguestfs/tests/guests/blank-disk.img:104857600B:file:512:512:unknown::; $ echo $? 0 This is why I hate parted. Anyway, I will post a v2 patch with this problem fixed.
