Bug Description

I have an associated VLANed network:

[root@jhenner-node-permanent ~(keystone_admin)]# nova-manage network list
id IPv4 IPv6 start address DNS1 DNS2 VlanID project uuid
2 192.168.32.0/24 None 192.168.32.3 8.8.4.4 None 100 de45db6defb34a5aa72ac5baaca7a1b5 7350769

When I try to delete:

[root@jhenner-node-permanent ~(keystone_admin)]# nova net-delete 7350769a-dc2c-4d37-9bd2-8d9ee57eef45
ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-e8e1f477-4313-4a0a-8017-89a349e04fa7)

The message is not informative enough.

There is a TB in log:

Is this really affecting the keystoneclient as well or was it simply that the wrong project was picked when the bz was submitted?

nova net-delete network is not informative enough

    Intially nova net-delete <Network ID> was raising an
    "InternalServerError" in case the requested network to
    delete was associated to any project.This error category
    “InternalServerError” is appropriate but the error
    message description is not informative enough.

    Now, when the command is not able to delete the requested
    network because it is associated with a project, a message
    stating “network must be disassociated from project
    <project-id> before delete” will be raised. Updated the
    code to raise the new error message.
    Closes-Bug: #1301373
