Re: [Rdo-list] RDO + floating IPs

I followed these guides on a clean Fedora 21 x86_64 server: https://www.rdoproject.org/Quickstart https://www.rdoproject.org/Floating_IP_range This on a baremetal box in a network outside of my control but in which there are 5 extra IP addresses assigned to me. It's quite possible that I'm missing something or doing something wrong, so here's exactly what I did: yum update -y && reboot --- systemctl disable NetworkManager systemctl enable network systemctl stop NetworkManager && ifdown enp0s25 && systemctl start network yum install -y https://rdo.fedorapeople.org/rdo-release.rpm yum install -y openstack-packstack yum-config-manager --disable openstack-kilo yum-config-manager --enable openstack-kilo-testing setenforce 0 packstack --allinone --provision-all-in-one-ovs-bridge=n

That succeeded, so I added a keypair and made sure the "default" security group allows all traffic. So next onto the neutron stuff: source /root/keystonerc_admin neutron net-create mynetwork --router:external (got a new network with type vxlan and id 4a30e2cc-b9f3-4ebd-b7ab-c35e38c3c75c) For the subnet I need the CIDR, gateway and the floating IP range. I'm not sure if I'm getting these right: * CIDR: `ip addr`, find my network interface (enp0s25), get it's inet value: 10.40.128.44/20 * Gateway: `ip route | grep default` -> default via 10.40.143.254 dev enp0s25 * And these 5 IP addresses are assigned to me: 10.40.128.80-10.40.128.84 neutron subnet-create mynetwork 10.40.128.44/20 --name mysubnet

(this creates a subnet with id 2e3d6966-a659-454c-8c38-d98ed3f105e5) neutron router-create myrouter (this creates a router with id fced82e6-9917-4053-a286-02838d0325fc) neutron router-gateway-set fced82e6-9917-4053-a286-02838d0325fc 4a30e2cc-b9f3-4ebd-b7ab-c35e38c3c75c (myrouter id and mynetwork id) neutron floatingip-create mynetwork With all that out of the way, I created another network+subnet for my VMs and added a myrouter's interface to it. Then I launched a cirros VM into that network and associated a floating IP from "mynetwork". The VM had some trouble with cloud-init: Starting network... udhcpc (v1.20.1) started Sending discover... Sending select for 192.168.0.4... Lease of 192.168.0.4 obtained, lease time 86400 cirros-ds 'net' up at 0.66 checking http://169.254.169.254/2009-04-04/instance-id failed 1/20: up 0.66. request failed failed 2/20: up 5.67. request failed failed 3/20: up 8.67. request failed failed 4/20: up 11.67. request failed ... once all 20 requests failed, it got to a login screen, but I could not ping or SSH into it: # ping 10.40.128.81 PING 10.40.128.81 (10.40.128.81) 56(84) bytes of data.
