On OpenStack controller /etc/resolve.conf is overwritten by NetworkManager after first reboot
Issue
After deploying the overcloud, the configuration of /etc/resolv.conf
is generated properly by cloud-init.
The problem is that after first boot, Network Manager overwrites the /etc/resolv.conf
file and removes nameserver
lines from the generated file. As a side effect Neutron is failing to start.
