Steps to reproduce:
1) Multi-node
2) Ubuntu
3) Neutron with VLAN segmentation
4) Ceph (cinder, glance, Ceph RBD for ephemeral volumes(Nova), Ceph RadosGW for objects(Swift API))
1 Controller(ceph-osd) + 1 Compute(ceph-osd)
From Horizon
1. Create VM1 (Image boot source - Launch instance (Boot from image (creates a new volume)) -- Device size 2-3 Gb )
2. Create snapshot from VM1 (for example Snapshot Name: image_snap1). Just tap on "Create snapshot" button into Horizon
3. Create VM2 (Launch instance (Boot from image ) --> (Image Name: image_snap1)
4. Create snapshot from VM2 --> " Error: Unable to create snapshot " and I get a 400 error in nova-api.log:
