<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Nova provides following REST API to get the details of instances provisioned in the given hypervisor.
<o:p></o:p></p>
<p class="MsoNormal">REST API: <span style="font-size:10.5pt;font-family:"Helvetica","sans-serif";color:#535353;background:white">
/v2/{tenant_id}/os-hypervisors/{hypervisor_hostname}/servers <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Helvetica","sans-serif";color:#535353;background:white">Ref:
<a href="http://developer.openstack.org/api-ref-compute-v2-ext.html">http://developer.openstack.org/api-ref-compute-v2-ext.html</a><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This API is consumed in horizon to report hypervisor’s instances details under Admin->Hypervisors panel.<o:p></o:p></p>
<p class="MsoNormal">According to the above API, nova never should allow same ‘<span style="font-size:9.0pt;font-family:"Courier New";color:#333333;background:white">hypervisor_hostname</span>’ for more than
<o:p></o:p></p>
<p class="MsoNormal">one hypervisors, as ‘<span style="font-size:9.0pt;font-family:"Courier New";color:#333333;background:white">hypervisor_hostname</span>’ used as identifier, but it allows. Due to this reason,
<o:p></o:p></p>
<p class="MsoNormal">horizon reports invalid data. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, this should be fixed on horizon, with the intention that, horizon should consume the API
<o:p></o:p></p>
<p class="MsoNormal">provided by nova as it’s and reports correct information. To address it, bug has been filed in horizon
<o:p></o:p></p>
<p class="MsoNormal">at <a href="https://bugs.launchpad.net/horizon/+bug/1402572">
https://bugs.launchpad.net/horizon/+bug/1402572</a> (using work-around, it’s being fixed)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This could be fixed at the nova side as well by using ‘<span style="font-size:9.0pt;font-family:"Courier New";color:#333333;background:white">hypervisor.id</span>’ as identifier instead of ‘<span style="font-size:9.0pt;font-family:"Courier New";color:#333333;background:white">hypervisor_hostname</span>’
<o:p></o:p></p>
<p class="MsoNormal">and use it in horizon and python-novaclient as well.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now this issue becomes inter-project related. And I’m looking for help to take it forward<o:p></o:p></p>
<p class="MsoNormal">to get fixed in kilo release. Could someone please help here?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<o:p></o:p></p>
