<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal">Our team has built 15+ compute nodes Openstack cluster, and with 200+ VM running on it. But we met a stranger issue and boring me several work days. Could anyone help me ?
<span style="font-family:Wingdings">J</span><o:p></o:p></p>
<p class="MsoNormal">The phenomenon is: if we create multi VMs in one request some or all of them cannot get IP from DHCP agent. Logs in quantum-server report
<b>“no active DHCP agent”</b> .I read official doc and enabled DHCP HA, but all DHCP agents for network are inactive while instance boot and suddenly change to active. “no active DHCP agent” still occurs. In other words, the agent heartbeat always go active
and immediately go inactive.<b> </b>I set agent_down_time = 120 but does not work
<span style="font-family:Wingdings">L</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">My quantum server log is very big and if anyone interesting this issue , I will send it to you.</span><o:p></o:p></p>
<p class="MsoNormal">Openstack is Grizzly, quantum using GRE mode, multi-host is enabled.<o:p></o:p></p>
