Hi, I am running Ubuntu Server 20.04 LTS on Virtualbox. I installed OpenStack (Xena release) through Devstack. Here is the content of my /opt/stack/devstack/local.conf file : [[local|localrc]] ADMIN_PASSWORD=secret DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD HOST_IP=10.0.2.15
I created an instance through Horizon. The security group contains the 2 rules needed (one to be able to ping and one to be able to ssh the instance). I also allocated and associated a floating IP address. And a ssh key pair.
Here is the configuration : openstack server list ---------------------------------+--------------------------+---------+

I cannot ping/ssh neither the fixed IP address or the floating IP address : ping -c 3 172.24.4.133 PING 172.24.4.133 (172.24.4.133) 56(84) bytes of data. --- 172.24.4.133 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2035ms
ping -c 3 192.168.233.165 PING 192.168.233.165 (192.168.233.165) 56(84) bytes of data. --- 192.168.233.165 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2035ms
Maybe that has something to do with the network namespaces configuration on Ubuntu. Does anyone know what could go wrong or what is missing ? Thanks for helping.
If You are trying to ping Floating IP directly from the host where devstack is installed (Virtualbox VM in Your case IIUC) then You should first have those floating IP addresses somehow reachable on the host, otherwise traffic is probably going through default gateway so is going outside the VM. If You are using ML2/OVN (default in Devstack) or ML2/OVS You probably have in the openvswitch bridge called br-ex which is used to send external network traffic from the OpenStack networks in Devstack. In such case You can e.g. add some IP address from the public network's subnet on the br-ex interface, like 192.168.233.254/24 - that will tell Your OS to reach that subnet through br- ex, so traffic will be able to go "into" the OVS managed by Neutron. -- Slawek Kaplonski Principal Software Engineer Red Hat
