Hello Everyone:<div><br></div><div>We can&#39;t create vm on a physical server with 64 CPU(as reported by /proc/cpuinfo). The error message is: &quot;cannot set CPU affinity on process 0&quot;</div><div><br></div><div>The following is the capabilities detected by libvirt:</div>
<div><br></div><div><div>      &lt;arch&gt;x86_64&lt;/arch&gt;</div><div>      &lt;model&gt;Westmere&lt;/model&gt;</div><div>      &lt;vendor&gt;Intel&lt;/vendor&gt;</div><div>      &lt;topology sockets=&#39;4&#39; cores=&#39;10&#39; threads=&#39;2&#39;/&gt;</div>
</div><div><br></div><div>I wonder if libvirt uses incorrect CPU topology information to set process affinity which lead to the error above.</div>
