It looks like it creates the file if it's not there -- it's just not smart enough to create /usr/etc if *that's* missing.  I reckon if you fix the path, everything will work fine.

I've no idea why that path was chosen even for XenServer (CentOS 5 based).  Something like /etc/openstack would be more appropriate in either environment, in my opinion.
