From the [0], it appears dnspython is NOT installed properly. I installed python-dnspython (not sure if its the same as dnspython) and still don't see *dns* or "base" under /lib/python2.7/site-packages/dns/rdtypes/ANY as [0] mentioned.

Clark,
I adjusted the version of greenlet/eventlet as required by other modules. here is the output:

The internet indicates [0] this is a problem with your dnspython installation. That post uses pip, but you are using distro packages so you may need to map things a bit to do further debugging. Hopefully, that helps get things sorted though.

We hit this error during "glance-manage db_sync": *ImportError: cannot import name greenpool.* Any idea what the root cause is and how to fix it? We have the following rpms installed (thought related).
`python2-greenlet-0.4.9-1.el7.x86_64.rpm` `python2-eventlet-0.18.4-2.el7.noarch.rpm` `python2-gevent-1.1.2-2.el7.x86_64.rpm`

Notice: /Stage[main]/Neutron::Db::Sync/Exec[neutron-db-sync]/returns: ImportError: cannot import name greenpool
I'm not familiar with the CentOS7 packaging, but as a sanity check I ran `pip install greenlet==0.4.9 eventlet==0.18.4` in a python2 virtualenv
wrote: then in a python2 interpreter `from eventlet import greenpool` runs successfully. I would try running this import by hand on your system to see if you can get any more information. Could be a packaging issue or potentially some sort of name collision between script names?
