Public bug reported: Because of race bug: https://bugs.launchpad.net/nova/+bug/1249065 http://status.openstack.org/elastic-recheck/index.html#1249065
When vmware driver using config drive, the IP address maybe not get injected, because of the missing of instance nw_info cache. Here is related code in nova vmware driver, and config drive codes: https://github.com/openstack/nova/blob/master/nova/virt/vmwareapi/vmops.py#L671 inst_md = instance_metadata.InstanceMetadata(instance, content=injected_files, extra_md=extra_md) https://github.com/openstack/nova/blob/master/nova/api/metadata/base.py#L146 # get network info, and the rendered network template if network_info is None: network_info = instance.info_cache.network_info in vmwareapi/vmop.py, the network_info is not passed to the instance metadata api, so metadata api will use instance.info_cache.network_info as the network info. But when instance.info_cache.network_info is missing, the network info will be empty, too. This is why sometimes, VMWare instances can not get IP address injected when using config drive. ** Affects: nova Importance: Undecided Assignee: Feng Xi Yan (yanfengxi) Status: Confirmed ** Changed in: nova Assignee: (unassigned) => Feng Xi Yan (yanfengxi) ** Changed in: nova Status: New => Confirmed ** Description changed: Because of race bug: https://bugs.launchpad.net/nova/+bug/1249065 http://status.openstack.org/elastic-recheck/index.html#1249065 When vmware driver using config drive, the IP address maybe not get injected, because of the missing of instance nw_info cache.
