Title:
"Error: Unable to connect to Neutron" is displayed when instance table
displays many instances over 150
Status in OpenStack Dashboard (Horizon):
Fix Released
Bug description:
When I displayed over 150 instances in a single page of instance table, I
always got "Error: Unable to connect to Neutron".
The instance table itself is displayed properly, so I think the priority is
low.
The error is RequestURITooLong from api.neutron.servers_update_addresses().
This method calls port_list with port_id filter parameters and too many
port_id can be passed.
As a result URI line becomes too long and the above exception is raised.
It is better not to display such error message and deal with
RequestURITooLong exception in api/neutron.
Note that we can avoid by setting API_RESULT_LIMIT to around 100 (the
default value is 1000).
