<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a Standard 2+2 system, I wanted to create 3 VMs with different vcpus each one. VCPUs were set on flavors:<o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">$ openstack flavor create --ram ${ram} --disk ${disk} --vcpus 4 flavor-1<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">$ openstack flavor create --ram ${ram} --disk ${disk} --vcpus 10 flavor-2<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">$ openstack flavor create --ram ${ram} --disk ${disk} --vcpus 14 flavor-3<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using <span style="font-family:"Courier New"">cpu_policy=dedicated</span> on flavors.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I could launch 2 VMs, with flavor-1 <span style="font-family:"Courier New"">
(--vcpus 4</span>) and flavor-2 (<span style="font-family:"Courier New"">--vcpus 10</span>). When tried to launch VM3 (<span style="font-family:"Courier New"">--vcpus 14</span>) I got the following error:<o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New";background:yellow;mso-highlight:yellow">Quota exceeded for cores</span><span style="font-family:"Courier New"">: Requested 14, but already used 14 of 20 cores (HTTP 403) (Request-ID: req-9ab18649-8796-4cad-8768-75f895ac48c1)<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Why the cores to use is limited to 20 if my hosts have 64 logical cores?<o:p></o:p></p>
<p class="MsoNormal">Are just 20 vcpus configured to be used by default?<o:p></o:p></p>
<p class="MsoNormal">How can I enable the rest of logical CPUs to use them?<o:p></o:p></p>
