<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">I am trying to figure out how to define a VM’s CPU Socket:Core:Threads topology. For licensing reasons we can’t create VM’s that map each core as a separate socket.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">KVM and libvirt both support the ability to define the socket:core ratio/topology, but I can’t see how to get openstack to request those capabilities.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I've tried the libvirt_cpu_mode and libvirt_cpu_model options, but they only seem to control the cpu's name, and what flags are passed through.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems that if I could only get nova to create the xml file with a topology section eg: <toplogy sockets=’1’ cores=’4’ threads=’1’/> then it would work.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This feature request seems related: <a href="https://bugs.launchpad.net/nova/+bug/1199019">
https://bugs.launchpad.net/nova/+bug/1199019</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But I’m not sure if it’s possible to define it within nova as yet anyway.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Cheers, Evan.<o:p></o:p></p>
