Will close this bug as a dup of
https://bugs.launchpad.net/nova/+bug/1228384 . As part of that fix, Phil
has implemented chunking of server ids when querying neutron for ports
of VMs. The above stack trace is for a quantum deployment, and Phil's
patch will be ported over to that deployment.

Title:
nova makes calls to neutron with out considering URI size limit
Status in OpenStack Compute (Nova):
New
Bug description:
Nova when requesting security group instance bindings for servers
makes a call to Neutron. When there are many servers, the URI size
grows beyond 8k with neutron throwing up 414 error message.
We could easily hit this bug in our deployment as we have several VMs running.
There is a similar bug while making net-list. It needed to make subnet
list internally and that would result in 414 if there are several
subnets that can make URI size too long. But subnet-list was internal
call and fix was appropriate in the neutron client.
Here the bug is while fetching sg instance bindings which is primary
call. Hence I feel the bug must be fixed in neutron API consumer which
is nova.
Also, there must be a general framework for all APIs to not to exceed
URI size limit or fix all calls with URIs which can extend beyond 8k
size limit.
