[Nova] too many tokens</font>
<br>
<hr noshade>
<br>
<br>
<br><font size=3>Hi everyone, </font>
<p><font size=3>I have a question regarding too many token generation in
nova when using quantumclient (also related to bug reports </font><a href="https://bugs.launchpad.net/nova/+bug/1192383"><font size=3 color=blue><u>https://bugs.launchpad.net/nova/+bug/1192383</u></font></a><font size=3>
+ </font><a href="https://bugs.launchpad.net/nova-project/+bug/1191159"><font size=3 color=blue><u>https://bugs.launchpad.net/nova-project/+bug/1191159</u></font></a><font size=3>)
</font>
<p><font size=3>For instance during the periodic task </font><font size=3 face="Calibri"><i>heal_instance_info_cache</i></font><font size=3>
(every 60s) nova calls quantum API method get_instance_nw_info
that calls _build_network_info_model (backtrace at the end of the mail).
</font>
<p><font size=3>During the execution of this method, 4 quantum clients
intances are created (all of them use the same context object) and for
each of them a new token is generated. </font>
<p><font size=3>Is it possible to change this behavior by updating the
context.auth_token property the first time a quantumclient for a given
context is created (so that the same token will be reused among the 4 client
instances) ? Is there some security issue that can appear?</font>
<p><font size=3>Thanks</font>
