I use Folsom releale.
I set OpenStack with Glance.
When I try to do a backup image of an instance, I get an error in nova-compute logs and in Glance log.
I use this API request to do a backup :
curl -i http://192.168.146.6:8774/v2/83a649b306f64942a3068f6a4fcf0eda/servers/8cc97452-f176-4c8a-b670-8dd40b8f944f/action -X POST -H "X-Auth-Project-Id: admin" -H "User-Agent: python-novaclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: 2cb3661781174a97864f8abe5612da2a" -d '{"createBackup": {"name": "Backup 1", "backup_type": "daily", "rotation": 2}}'
The snapshot is created but the older backup are not deleted.
I opened two bug, this one for Glance and another one for Nova :

I investigated the problem and I think it's not Glance bug.
When I made a backup on VM, Nova requests Glance to get the list of backup image associated to the instance. And with this list, Nova can clean backup images according to rotation parameter.
To get this backup image list, Nova use the 'marker' and 'limit' parameters of Glance API.
But the first request sent by Nova sets the 'marker' parameter to 'None' and Glance doesn't accept this value and reponds with invalid parameter exception.
So I don't think it's a Glance bug. Or, do you think, Glance should accept 'marker' parameter seted to 'None' or 'none' like the 'is_public' parameter ?
