[Bug 1349841] [NEW] "Error: Unable to connect to Neutron" is displayed when instance table displays many instances over 150

 

Public bug reported:

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).
