The zero-size image does not sound correct ... unless there's actually
no data stored in glance because the snapshot did not complete properly
or something. Check the output of either 'glance image-show <UUID>' or
'openstack image show <UUID>' to make sure that the image size is
nonzero and that the image status is 'active'. Otherwise something went
wrong during the snapshot process.
If Glance reports the image as having a size and being active, you could
add the --debug flag when you download the image. That might give you
more information to troubleshoot with.
