Hi Leontiy,

could you please describe steps to reproduce and add more information - for example, attach diagnostic snapshot?

Status changed to Incomplete because we need to provide more information or access to the lab for Glance team. Please, do this and change the status of the issue to Confirmed or Invalid when you will find the root of the issue.

[Timur Nurlygayanov (tnurlygayanov)]

Also, please, specify MOS version and build number - is it MOS 6.1 or MOS 7.0?

[Leontii Istomin (listomin)]

Updated bug description. I believe we can reproduce the issue if perferm the following steps:
1. create an instance
2. create snapshot of the instance
3. boot instance from the snapshot

[Timur Nurlygayanov (tnurlygayanov)]

Leontiy, thank you!

[Leontii Istomin (listomin)]

can be reproduced with the following symptoms:
1. create an instance
2. create snapshot of the instance
3. execute "glance --os-image-api-version 2 image-list" command. Result of the command:
http://paste.openstack.org/show/377616/

related bug in upstream https://bugs.launchpad.net/python-glanceclient/+bug/1447193
fix was proposed in upstream https://review.openstack.org/#/c/176379

[Leontii Istomin (listomin)]

have tried patch https://review.openstack.org/#/c/176379.
It works well. snapshot_server rally scenario has been passed successfully.

after creating snapshot image-list with v2 works well:

[Timur Nurlygayanov (tnurlygayanov)]

Verified on my QA lab, MOS 7.0 ISO #265:

1. create an instance
2. create snapshot of the instance
3. execute "glance --os-image-api-version 2 image-list" command.

Result:
root@node-1:~# glance --os-image-api-version 2 image-list
