Hi all,
i've a controller which is running all service and a secondary controller which
is un multi_host so it's running compute network and api-metadata. From the
dashboard i can successfully create snapshots of instances running on the
controller but when i try to create a snapshot of an instance on a compute node
i get in its logs:
==> /var/log/nova/nova-compute.log <==

any idea?
Using nova create-image works but it creates a new image, not a snapshot (as
the dashboard shows)
