[Bug 1758260] [NEW] Create instance throws TypeError: argument of type 'NoneType' is not iterable in nova-conductor
Public bug reported:
Installed a brand new Openstack Queenson Ubuntu 16.04 following the
OpenStack documentation.
I have 1 controller and 1 compute (kvm) nodes so far, no storage yet.
All are registered properly:
```
$ sudo -u nova nova-manage --use-json cell_v2 list_cells
+-------+--------------------------------------+--------------------------+------------------------------------------------+
| Name | UUID | Transport URL | Database Connection |
+-------+--------------------------------------+--------------------------+------------------------------------------------+
| cell0 | 00000000-0000-0000-0000-000000000000 | none:/ | mysql+pymysql://nova:****@localhost/nova_cell0 |
| cell1 | d30a8c57-dad1-406f-9ff1-50d93dc70b2b | rabbit://openstack:****@ | mysql+pymysql://nova:****@localhost/nova |
+-------+--------------------------------------+--------------------------+------------------------------------------------+
```
And:
```
sudo -u nova nova-manage cell_v2 list_hosts
+-----------+--------------------------------------+----------+
| Cell Name | Cell UUID | Hostname |
+-----------+--------------------------------------+----------+
| cell1 | d30a8c57-dad1-406f-9ff1-50d93dc70b2b | grunt01 |
+-----------+--------------------------------------+----------+
```
When I create an instance:
```
$ openstack server create --flavor m1.nano --image cirros \
--nic net-id=$(openstack network show demo -c id -f value) \
--security-group default
--key-name xxxx
first -test
```
The image gets created but stays stuck in the BUILD state.
The logs on the compute noad (/var/log/nova-compute.log) never get any
entry written.
The version for nova is:
```
$ dpkg -l | grep nova
ii nova-api 2:17.0.0-0ubuntu1~cloud0 all OpenStack Compute - API frontend
ii nova-common 2:17.0.0-0ubuntu1~cloud0 all OpenStack Compute - common files
