VNF OpenStack VIM creation error when enable K8S VIM

[Trinh Nguyen]

The VNF for OpenStack VIM creation is in CREATE_IN_PROCESS state forever and then ERROR when I enable K8S VIM. Also, I cannot delete the error VNF.

Here are the steps to reproduce the error:

1. Deploy devstack with Kubernetes VIM enable.

https://docs.openstack.org/tacker/latest/install/kubernetes_vim_installation.html

2. Register an OpenStack VIM and make it the default:

os_vim.yaml:

auth_url: 'http://<my-devstack-ip>/identity'
username: 'admin'
password: 'devstack'
project_name: 'admin'
project_domain_name: 'Default'
user_domain_name: 'Default'
type: "openstack"

tacker vim-register --config-file os_vim.yaml osvim --is-default True

3. Create a VNFD template:

wget https://raw.githubusercontent.com/openstack/tacker/master/samples/tosca-templates/vnfd/tosca-vnfd-openwrt.yaml

tacker vnfd-create --vnfd-file tosca-vnfd-openwrt.yaml osvnfd

4. Create the VNF:

tacker vnf-create --vnfd-name osvnfd osvnf

I just tried to reproduce the bug and I got this error:

http://paste.openstack.org/show/686132/

This time the PENDING time is short and it went to ERROR pretty fast.

Here is my test environment:

+ Fresh Ubuntu 16.04
+ Devstack: master
+ Python Tacker Client: master
+ Tacker: master
+ K8S VIM: enabled
+ OpenStack vim template: like above

The VNFD I used: https://github.com/openstack/tacker/blob/master/samples/tosca-templates/vnfd/tosca-vnfd-hello-world.yaml

Looks like it's a nova issue. After I restart nova, it works just fine.
