Hi All,


We have deployed ONAP on Vanilla OpenStack Mitaka (On top of CentOS 7). Using 
the following YAML and env files:

https://gerrit.onap.org/r/gitweb?p=demo.git;a=blob;f=heat/OpenECOMP/onap_openstack_float.yaml;h=659f94c93b9c5dfae02031ddcae82161ce927318;hb=refs/heads/master

https://gerrit.onap.org/r/gitweb?p=demo.git;a=blob;f=heat/OpenECOMP/onap_openstack_float.yaml;h=659f94c93b9c5dfae02031ddcae82161ce927318;hb=refs/heads/master



Once ONAP stack is created, the SDC, MSO and Robot VMs remain accessible till 
they reboot as part of their respective install script execution. The install 
script for each VM is:

1)      SDC - /opt/asdc_install.sh

2)      MSO - /opt/mso_install.sh

3)      Robot - /opt/robot_install.sh



We found that in each script the following line is written which changes the 
NIC interface name from ens[x] to eth0

sed -i "s/ens[0-9]*/eth0/g" /etc/network/interfaces.d/*.cfg



Due to this after reboot each VM becomes inaccessible. If the above line is 
commented, the issue does not happen.



We want to know the reason for changing the Interface name.

We searched and found some discussions that the Ubuntu-16.04 does not work well 
with NIC name as ensX however, we didn’t see any such problem.





With Regards,

Arun Arora
