Comment 4 for bug 2008064

@Ayumu: thanks for the quick response. You can see that image-show says this:

| disk_format | raw |

but what the image format actually is, according to qemu-img:

    "format": "qcow2",

The way to fix this is to look in your CI setup for where you upload the image. If you are using python-openstackclient, if you don't specify the --disk-format, openstackclient sets 'raw' as the default. So add

  --disk-format qcow2

to your 'openstack image create' statement.
