Backport to stable/newton: https://review.openstack.org/#/c/406634/ This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2017:1585 |
Description of problem: The following line in OsNetConfigMappings: resource of this example is using "eth0" network device name to get a eth address as "system identifier" eth_addr=$(/sbin/ifconfig eth0 | grep ether | awk '{print $2}') On a CentOS or RHEL deployment on baremetal hardware would not have an "eth0" interface. Because of Consisten Netowork Device Naming[1], the interface can be "emX", "enoX" or "pXpX" etc. [1] https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/ch-Consistent_Network_Device_Naming.html Version-Release number of selected component (if applicable): How reproducible: Try os-net-config-mappings on a hardware system. Due to Consistent Device Names being enabled by default the "/sbin/ifconfig eth0" command returns an error such as: 'eth0: error fetching interface information: Device not found' Actual results: NIC mapping file is not created, because the method to identify the different host does not work when Consistent Network Device Naming is enabled. Expected results: The host should be identified even with Consisten Network Device Naming enabled, and the mappings.yaml file should be written.
