I could not get to it now so I can not validate, but...
I have in roles/cloud_compute/tasks/main.yml
- lineinfile: dest=/etc/sysconfig/network-scripts/ifcfg-eth1 regexp="^ONBOOT=" line="ONBOOT=yes"
  notify:
    - restart network
- lineinfile: dest=/etc/sysconfig/network-scripts/ifcfg-eth1 regexp="^NETMASK=" line="NETMASK=255.255.255.0"
  notify:
    - restart network
- lineinfile: dest=/etc/sysconfig/network-scripts/ifcfg-eth1 regexp="^IPADDR=" line="IPADDR={{compute_private_ip}}"
  notify:
    - restart network
- lineinfile: dest=/etc/sysconfig/network-scripts/ifcfg-eth1 regexp="BOOTPROTO=" line="BOOTPROTO=none"
  notify:
    - restart network
Can it be that there is no MAC binding in udev so eth1 can become eth0 and vice versa?
Or something else?

BTW it does not block me any more. I managed to change endpoints to use internal IP. But still nice to have.
