Thanks for the feedback, but I am assuming that this by itself is not
enough.
I guess I should have created the DB before.....
Any other actions that must be done before that?
Best,
George
To add cells you need to issue the following command after nova
service-list lists all your compute nodes as up state!
nova-manage cell_v2 simple_cell_setup --transport-url $transport_url
Where
$transport_url=rabbit://{rabbit_user}:{rabbit_pass}@{rabbit_host}:{rabbit_port}
This command will populate the db and add a transport_url option in
nova.conf on the controller.
Again, you need to issue this command after all computes node show as
up state in nova service-list, otherwise you will still be unable to
spawn instances.
I might have written the command wrong from the top of my head, but
issue a nova-manage help cell_v2 to see the appropiate option.
I am mailing you directly because for some reason i am unable to send
to thr mailing list.
When you reply to the mailing list olease put this mail in it so
others can see it too if they have the same problem.
Thanks,
Mihai

As you have pointed out there is also this bug:
https://bugs.launchpad.net/openstack-manuals/+bug/1663485 [17]
that will not allow me to spawn an image until the Cells have been
configured properly.
So I am looking for a permanent solution...

Mihai, I am putting the list here as well...
No I didnt add the [placement] section in nova.conf on the
controller but adding it only on the compute node brought it
online.
I dont know yet if I can spawn an instance and if what you are
saying is mandatory in Ocata in order to spawn one since I havent
reached that part of the installation guide. The verification
though
of the compute services went OK as supposed to by the
installation
guide.

Hi,
Did you also add the [placement] section in nova.conf on the
controller?
Also in Ocata AFAIK you also need to create cell_v2 with
nova-manage
or else you wont be able to spawn instances.
But first add the placement section on the controller too in
nova.conf
and the computes shoukd come online.

All,

Unfortunately I have stuck at deploying the Compute Node

the following

Did it actually kill the nova-compute service or just
complain in
the
logs? The release notes for nova in Ocata say:
The nova-compute worker now communicates with the new
placement API
service. Nova determines the placement API service by
querying the
OpenStack service catalog for the service with a
service
type of
placement. If there is no placement entry in the
service
catalog,
nova-compute will log a warning and no longer try to
reconnect to the
placement API until the nova-worker process is
restarted.

Hi Chris,
it is constantly printing this output in the log and also
prevents
the openstack-nova-compute.service
from being shown as Active (running) when doing a "systemctl
status
openstack-nova-compute.service"
There is already a proposed bug fix
https://review.openstack.org/#/c/440140/ [1] [2] which seems
to solve
this problem
For reference I ve added the following in the "placement"
section
of nova.conf in the compute node
[placement]
# ...
os_region_name = RegionOne
project_domain_name = Default
user_domain_name = Default
project_name = service
auth_type = password
username = nova
password = NOVA_PASS
auth_url = http://controller:35357/v3 [2] [3]
Best regards,
George
