LFS264: lab1, step 5, APEX setup command fails

eddgest

Hi,
the prerequisite to execute the labs for this course fails: I can login to my google-VM, but when I execute
opnfv-deploy -v --debug -n network_settings.yaml -d os-nosdn-nofeature-noha.yaml
it fails with the following stack-trace:
Traceback (most recent call last):
File "/bin/opnfv-deploy", line 10, in
sys.exit(main())
File "/usr/lib/python3.4/site-packages/apex/deploy.py", line 266, in main
vcpus=args.virt_cpus
File "/usr/lib/python3.4/site-packages/apex/virtual/utils.py", line 68, in generate_inventory
'ipmi_ip': get_virt_ip(),
File "/usr/lib/python3.4/site-packages/apex/virtual/utils.py", line 40, in get_virt_ip
tree = ET.fromstring(virsh_net_xml)
File "/usr/lib64/python3.4/xml/etree/ElementTree.py", line 1335, in XML
parser.feed(text)
xml.etree.ElementTree.ParseError: syntax error: line 1, column 0

It seems there is a parsing error for some file.

Any hints ?
I have attached the apex_deploy.log as well as ther terminal output of my session.

Thanks

Hi,
thanks for looking into this, but it is still happening.
Find the terminal log attached.

Hello,

I have the same issue with error:

2019-01-11 10:34:03,103 ERROR: Ansible playbook failed. See Ansible logs for details.

I try using the suggested workaround from vmuthukrishnan, but I got the same error.

Attached:

• konsole-output-2019.01.11 => console commands I executed
• nohup-2019.01.11 => printouts from opnfv-deploy -v --debug -n network_settings.yaml -d os-nosdn-nofeature-noha.yaml --virtual-default-ram 16 --virtual-cpus 8
• apex_deploy-2019.01.11

Please help us to fix this issue and be able to proceed with the Labs.

Best regards,

Hi,

It appears that you do not have enough vCPUs on the GCP instance to start OPNFV deployment.

gereon@LF-base-machine:~$ gcloud compute instances create opnfv-instance-00 --zone=us-central1-f \

--custom-cpu=8 --custom-memory=52GB --min-cpu-platform="Intel Haswell" \
--image=aarna-opnfv-euphrates-51-pub-05012018-00 --image-project=onap-177920 \
--boot-disk-type "pd-standard" --boot-disk-size=300GB

opnfv-deploy -v --debug -n network_settings.yaml -d os-nosdn-nofeature-noha.yaml --virtual-default-ram 16 --virtual-cpus 8

Your GCP instance has 8 vCPU's, and the OPNFV deployment also uses 8 vCPUs, which will not be sufficient.

Please create GCP instance with 32 vCPUs (this is what we recommend).

Hope that helps.

Hello,

Thanks a lot for your replay! I have tried to create a GCP instance with 32 vCPUs, but I got the following error:

gcloud compute instances create opnfv-instance-00 --zone=us-central1-f --custom-cpu=32 --custom-memory=52GB --min-cpu-platform="Intel Haswell" --image=aarna-opnfv-euphrates-51-pub-05012018-00 --image-project=onap-177920 --boot-disk-type "pd-standard" --boot-disk-size=300GB
ERROR: (gcloud.compute.instances.create) Could not fetch resource:
- Quota 'CPUS' exceeded. Limit: 8.0 in region us-central1.

The problem is that as a free GCP user I have limit of 8 vCPUs for all available zones - see attached screen-shoot.

Any suggestions how we can execute the Labs using the free GCP Quotas?

Best regards,
Todor

Unfortunately, the labs cannot be done on a free GCP tier. We actually advise in the course thst some costs are associated with them, due to the complexity of the labs and the environment needed.
