Hi Vish,

I had already a setting:

glance_api_servers=10.0.0.1:9292

i've also tried to add

glance_host=10.0.0.1

but i got the same error.. Also, after changing configuration and restarting nova-compute restarts all instances, is that normal?

Best

Alessandro

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:
