OpenStack Dashboard (Horizon)

What is the interaction between dashboard and nova client?

Asked by David Kranz

I have installed openstack using "devstack". I can successfully create a vm either by using the dashboard or by the command 'nova boot'. I was surprised to see that the vms created by dashboard did not show up in 'nova list', and the vms created by 'nova boot' did not show up in the dashboard, even after refresh. Is this by design?

Also, I see lines in the log like this that have [error]. Are these really errors?

simple answer...
there is none (at least not currently)
nova client interacts with euca2ools/nova-manage (not keystone)
dashboard interacts with keystone (not euca2ools/nova-manage)

From what I understand, this will change in the future (maybe)

Going forward I think it would be a requirement that the data controlled by the dashboard could also be driven from the command line so I hope that gets fixed!
