Hello,
what is the state of the instance before asking the snapshot ? Is it
running or paused ?
Check on the hypervisor when the snapshot starts if you see files in these
folders:
/var/lib/libvirt/qemu/save/
/var/lib/nova/instances/snapshots/
How is your glance implemented ? Also with ceph rbd ? Remember that a "nova
snapshot" is a glance image.
