<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to migrate controller and compute VMs installed with Openstack-Ansible across systems with following approach.<o:p></o:p></p>
<p class="MsoNormal">This is mainly to minimize the deployment time in the Jenkins CI environment.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Export steps:<o:p></o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Power off the VMs gracefully.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">virsh dumpxml ${node} > $EXPORT_PATH/${node}.xml<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">cp /var/lib/libvirt/images/${node}.qcow2 $EXPORT_PATH/$node.qcow2<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">create a tar ball for the xml’s and qcow2 images.<o:p></o:p></li></ol>
<p class="MsoListParagraph"><o:p> </o:p></p>
<p class="MsoNormal">Import steps:<o:p></o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">cp ${node}.qcow2 /var/lib/libvirt/images/<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">virsh define ${node}.xml<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">virsh start ${node}<o:p></o:p></li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After the import of the VMs, The openstack services (neutron-server, DHCP agent, Metering agent, Metadata agent, L3 agent, Open vSwitch agent, nova-conductor and nova-comute) are started in random order.<o:p></o:p></p>
<p class="MsoNormal">This causes neutron and nova is not able to find DHCP agent and compute accordingly to bring up the tenant VM and throws the error [1].<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have also tried to boot compute VM followed by controller VM. It also doesn’t help.<o:p></o:p></p>
<p class="MsoNormal">Could you please let me know what is going wrong here ?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
