[Nitish Krishna Kaveri (nitishk)]

I don't see any mention of kernel_upgrade or kernel_version in roles/node/vars/main.yml:

https://github.com/Juniper/contrail-ansible/blob/R4.0/playbooks/roles/node/vars/main.yml

Or even in mainline code:

https://github.com/Juniper/contrail-ansible/blob/master/playbooks/roles/node/vars/main.yml

How did u get this code in that file?

Did u copy the code from mainline?

[Vedamurthy Joshi (vedujoshi)]

Nitish, like i mentioned, i did the changes manually so that i could proceed.
