Public bug reported:
OS: Fedora (64 bits) – Linux –. Last available component: qemu-
img.x86_64 2:2.11.2-2.fc28
Description: version of disk image format not exhibited using the 'qemu-
img info' command.
Command 'qemu-img info qcow2 [image-file-name.img]' produces this stderr
message:
qemu-img: Expecting one image file name
Try 'qemu-img --help' for more information
How to reproduce in terminal:
1. Create a VM using Raw disk image format
2. Run either commands 'qemu-img info -f raw [image-file-name.img]', 'qemu-img
info [image-file-name.img]'.
3. Run either commands 'qemu-img info -f qcow2 [image-file-name.qcow2]',
'qemu-img info [image-file-name.qcow2]'.
Actual result: output model resulting from step .2 exhibits following
informations:
image: image-file-name.img
file format: raw
virtual size: _G (_ bytes)
disk size: _G
Output model resulting from step .3 exhibits following informations:
image: image-file-name.qcow2
file format: qcow2
virtual size: _G (_ bytes)
disk size: _G
cluster_size: _
