After read the code of puppet, I notice it will rewrite the Ethernet configuration, so I test it by myself, it works after re-run the packstack. Thanks! -Best Regards, Andy 发件人: rdo-list-bounces(a)redhat.com [mailto:rdo-list-bounces@redhat.com] 代 表 梅磊 发送时间: 11 December 2014 11:33 收件人: rdo-list(a)redhat.com 主题: [Rdo-list] change ethernet name in answer file Hi experts, After using RDO to deploy all in one openstack(Juno), I notice I use the wrong Ethernet as the public interface and private interface, so can I change the ethernet name in answer file and reinstall the openstack? Does it will take effect? -Best Regards Andy
