20. Now we are done configuring both parent and child…
21. How do the parent and the child know about each other now?
22. On parent, we will run the command:
nova-manage cell create --name=child --cell_type=compute --
username=guest --password=password --hostname=<child ip> --
port=5672 --virtual_host=/ --woffset=1.0 --wscale=1.0
23. On the child, we will run the command:
nova-manage cell create –name=parent --cell_type=api --
username=guest --password=password --hostname=<parent ip> --
port=5672 --virtual_host=/ --woffset=1.0 --wscale=1.0
24. Let’s try to build an instance in this cell environment…
