Hello, I hava installed openstack Liberty using vxlan, though there are no error in logs and I can create vm in computer node, I can't ping external network either in vm or in router namespace. In my controller node, there is only one Network Interface, and my tenant_network_type is vxlan. My question is how many network interfaces is required at least, if one network interface can achieve the goal, how should I edit the conf ? Thanks Li yulei -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack/attachments/20160412/57aaf0d8/attachment.html>
