Hi,
Reference/context: https://ask.openstack.org/en/question/28297/cloud-init-nonet-waiting-and-fails/
The trusty image provided by http://cloud-images.ubuntu.com/trusty/ contains an eth0 interface configured as dhcp in /etc/network/interfaces.d/eth0.
When I boot this image in an Openstack non-dhcp networking environment, cloud-init configures the static IP provided by Neutron directly in /etc/network/interfaces (not interfaces.d).
This means I now have two eth0 devices configured, in two different files.
Booting 20 VMs with the same image yields around 50-60% of VMs that are not reachable by network.
Soft rebooting a VM in this state or doing and "ifdown eth0 && ifup eth0" will make it ping.
I removed the the eth0 interface file in /etc/network/interfaces.d/eth0 from the image, booted another round of VMs and all of them worked fine.
Now, I see three possible outcomes:
- If eth0 is present in /etc/network/interfaces.d, cloud-init configures/re-configures that interface
- If eth0 is present in /etc/network/interfaces.d, cloud-init deletes it and configures /etc/network/interfaces
- Ubuntu cloud images ships without eth0 being configured by default |
