Comment 1 for bug 1342313

This particular case you are talking about is a python-neutronclient/neutron-metadata-agent issue, so I'm not sure why you assigned MOS Nova team to fix it.

At the same time, I agree, that we might have similar issues in nova/python-novaclient, although I haven't seen ones yet. Can you point me to specific problems in Nova?

We'll need to find out, if we can fix this once and for all, or the fixes will be per-case as with the python-neutronclient fix you mentioned here.
