Hi Narinder,

I'm new to open source platforms and so it took a while for me to get used to mailing lists and getting support from the community but I should definitely thank you for your help and support so far. I would like to take this opportunity to thank Heather as well for guiding me through certain issues. I guess I should have changed the subject line which I did now. The error I am facing currently is related to deployment of juju OAI ( Open Air Interface) bundle in MAAS cloud. I would really appreciate if someone can assist me in triaging this issue.Thank you so much for your time!!

Regards,
Navin S

I am sorry Navin I can not spend more time on debugging your environment as I have more commitment from Canonical but please free to engage juju community on irc freenode #juju channel they should able to help you. As juju community is very active and they can help you with your concerns.
Thanks and Regards,

Hi Heather,
As advised, I brought up MAAS cloud and had JUJU bootstrap successfully to that of MAAS. Once bootstrap was done, I tried deploying the JUJU OAI bundle( cs:~navid-nikaein/bundle/oai-nfv-4g-1) but landed up with the following error. It would be more than a help if you could kindly help me troubleshoot this issue . Thank you so much!!

Just to let you know that I am using "nosdn" scenario and not Opencontrail. Thanks for your continued support, much appreciated!!

Navin,
The error thrown by juju is received from OpenStack when we tried to boot an instance. OpenStack is requiring the name or uuid of the network to use because it doesn't know which network to choose. The fix for that error is using --config network=<network> during bootstrap.
Were there any hints in the nova log regarding details for the No Valid Hosts failure? When you manually booted the OpenStack instance, did you need to specify `--nic net-id=net-uuid` or `--nic net-name=network-name`?
Unfortunately I'm not familiar with Opencontrail SDN.

Also, I am able to boot up an instance manually in the OpenStack cloud using m1.medium and the status of the instance reads "Active". Any insights on the above error please?
I see my error related to this post - https://bugs.launchpad.net/ juju/+bug/1570219

Navin,
From your email, it appears that juju is finding the network specified correctly. Is there more information leading to believe that is the problem?
Are you able to boot an instance within the OpenStack Cloud specifying the same network, using the m1.medium flavor? I'd recommend checking the nova logs to see what more info can be found on the cause of the No Valid Host error.

Hi all,
I am fairly new to JUJU and am currently working on deploying OAI (Open Air Interface) on OPNFV using JOID installer.
H/W used : HP- Proliant DL380G6 G6 bare metal box
OS : Ubuntu 16.04 Xenial
I have spun up 3 VM's using MAAS (Metal as a Service) that's been deployed in the bare metal box. JUJU has been installed in the bare metal and I am trying to bootstrap it to Openstack cloud whose control and compute nodes are hosted on these VM's. Ultimate objective is to deploy OAI model using JUJU in the Openstack cloud.
During bootsrapping using the below command, it throws an error "failed to bootstrap model: cannot start bootstrap instance: cannot run instance: No valid host was found." I believe the issue is with the Openstack's network UUID that's passed on as a parameter while bootstrapping.
juju bootstrap openstack --debug --config image-metadata-url=$SWIFT_URL/ simplestreams/images --config use-floating-ip=true --config network=private
10:36:16 DEBUG juju.provider.openstack provider.go:1022 using network id "383fd64b-4c4c-497d-809d- 3bcf8ed72e1c"

10:36:33 ERROR juju.cmd.juju. commands bootstrap.go:496 failed to bootstrap model: cannot start bootstrap instance: cannot run instance: No valid host was found.
From the error log I see that it uses network id "383fd64b-4c4c-497d-809d- 3bcf8ed72e1c" which is the network id of private subnet and I confirmed that from the Openstack GUI (PFA screenshot), but then fails to bootstrap. I am stuck at this point in time and any response would be considered more than a help. Thank you all!!
