Hi, I'm installing Openstack manually and that means I don't use automation tools such as Devstack or Packstack.
During the setup process, because of the problem, I have not been able to progress for three days at this stage! I guess that is caused by network settings. First of all, after I describe the network environment I'm in (here is a school), you'll understand what my problem is. Here, for Internet connection, every node (PC or server) needs manual IP like below figure. https://imgur.com/4ZkdxqO I made up the figure, guessing how the network structure is organized. So, it could be wrong. What is remarkable is that every time I reboot, a bridge of which name starts with 'brqf' is created, and suddenly the Internet does not work on the controller node. The local network is normally connected and DNS_PROBE_FINISHED_BAD_CONFIG error occurs in the internet browser. If I remove the bridge, Internet becomes available again. The weird bridge also emerges on the controller node, but Internet is working on the node well. In addition, I heard that compute node needs more than 2 NIC but, I'm curious about how to configure that. In fact, I was using this link ( https://docs.openstack.org/install-guide/openstack-services.html#minimal-deployment-for-queens) to proceed with the installation. And I choose 'Provider network' from the Openstack networking options (Provider networks and Self-service networks). After I finished minimal installation for Queens, I attempted to create an instance. However, the error occurs and it is following: 2018-11-16 15:12:05.491+0000: libxl: > libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge > online [7254] exited with error status 1 > 2018-11-16 15:12:05.491+0000: libxl: > libxl_device.c:1286:device_hotplug_child_death_cb: script: ip link set > vif1.0 name tap4dcb475d-8f failed > 2018-11-16 15:12:05.491+0000: libxl: > libxl_create.c:1522:domcreate_attach_devices: Domain 1:unable to add vif > devices The message is from libxl (libvirt) log (/etc/libvirt/libxl/libxl-driver.log). I suppose that the error is caused due to wrong network setting in the host or wrong network configuration of Openstack. But, I was not able to start solving this problem because I do not know what I should do first. I have no idea about that problem at all ! Please help me.
