Hi,
I'm trying to migrate controller and compute VMs installed with
Openstack-Ansible across systems with following approach.
This is mainly to minimize the deployment time in the Jenkins CI environment.
Export steps:
1. Power off the VMs gracefully.
2. virsh dumpxml ${node} > $EXPORT_PATH/${node}.xml
3. cp /var/lib/libvirt/images/${node}.qcow2 $EXPORT_PATH/$node.qcow2
4. create a tar ball for the xml's and qcow2 images.
Import steps:
1. cp ${node}.qcow2 /var/lib/libvirt/images/
2. virsh define ${node}.xml
3. virsh start ${node}
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.
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].
I have also tried to boot compute VM followed by controller VM. It also doesn't
help.
Could you please let me know what is going wrong here ?
