MAC address conflict
You might encounter MAC address conflict while installing cloud-init.
Sometimes when cloud-init fails to clean the cache data, or when you add a new network, you might see the MAC address conflict issue.
Remove the MAC address information. For more information about how to remove
the MAC address information and open required port, see the
No hard-coded MAC address
information information in the OpenStack Virtual Machine Image Guide.
- The /etc/sysconfig/network-scripts file path that is mentioned in the 'No
hard-coded MAC address information' section for the
HWADDRapplies for Red Hat® Enterprise Linux® only. For SUSE Linux, the
HWADDRpath is /etc/sysconfig/network. For example, for
ifcfg-eth0adapter, on SUSE Linux remove the
HWADDRline from /etc/sysconfig/network/ifcfg-eth0.
- Files 70-persistent-net.rules and
75-persistent-net-generator.rules mentioned in the
No hard-coded MAC address informationsection are required to add or remove network interfaces on the virtual machines after deployment. Ensure that you save these files so that you can restore them after deployment is complete.
