Public bug reported:

This comes from here:
https://bugs.launchpad.net/horizon/+bug/1349841

When number of ports attached to a vm is more than 200+, so this exception is happening
https://github.com/openstack/horizon/blob/master/openstack_dashboard/api/neutron.py#L568
I see that type of filter_values is set.

So on this line https://github.com/openstack/horizon/blob/master/openstack_dashboard/api/neutron.py#L576
filter_values becomes a list with one set element.
After that all_filter_len,  allowed_filter_len and chunk_size calculated wrong, and resources returned from that procedure is empty.

See comment on line 554 here:
https://review.openstack.org/#/c/110291/2/openstack_dashboard/api/neutron.py

You can reproduce it by attaching 200+ ports to one vm, so url length of
a request to neutron-server api with list of all the ports is more than
8192, or by attaching just several ports to a vm and reducing max url
length in neutron server.

Let me know if  additional information needed.
