hi, Mikko Elomaa

It need more log about nova-api.log and nova-compute.log

[Markus Zoeller (markus_z) (mzoeller)]

@Mikko: It could be an configuration issue. Please attach the conf files from Nova (etc/nova/nova.conf) and Neutron (etc/neutron/*.conf) from your controller node.

[Markus Zoeller (markus_z) (mzoeller)]

@Mikko: To be precise, the error message you get is:

    NoSuchOptError: no such option in group neutron: auth_plugin

and I think it should be "auth_type", as stated in [1]:

    [neutron]
    # Authentication type to load (unknown value)
    # Deprecated group/name - [DEFAULT]/auth_plugin
    #auth_type = <None>

This commit migrated from keystoneclient to keystoneauthrefs to load the config options: https://git.openstack.org/cgit/openstack/nova/commit/?id=f19ddc4

I have Openstack Mitaka installed on Ubuntu 16.04 xenial xerus; I have the same error when launching a new instance from Horizon Dashboard.

1. If launched via nova boot; the operation is successful 100%.
2. If via Horizon, I receive a popup: Error: Unable to create the server. Knowing that not a single error is logged to any component (nova, neutron ...) log files.

I guess, it is a security group compatibility issue when submitting from Horizon.

[Augustina Ragwitz (auggy)]

I've added Horizon to this bug and am marking invalid since everything appears to be working correctly in Nova. If there is an issue the Nova team needs to address, please provide those details and feel free to reopen this issue for Nova.

[Matt Borland (palecrow)]

We'll need more specifics about the Horizon interaction to help debug this problem, like what options were selected in the launch-instance wizard, which version, etc., and a comparison of the specific commands/options from the CLI to compare what is being asked of Horizon when it launches the instance.
