2017-04-20 17:28:14 -0500 answered a question How to configure multiple Floating IP for one instance?

Well, this one is old, but in case anyone need this. You can assign as many floating ip as you have interfaces Assuming you already have a setup with private networks and corresponding external networks.

  1. Add second network port to instance
  2. Ifup interface (private network)
  3. Let's say you added eth1 with
  4. network and ip and gateway as
  5. Attach second floating ip
  6. Add 2nd routing table and routing rules.

echo "1 rt2" >> /etc/iproute2/rt_tables

ip route add dev eth1 src table rt2

ip route add default via dev eth1 table rt2

ip rule add from table rt2

ip rule add to table rt2

And there you go, you have multiple floating ip's. It's useful for any setups with already existing networking infrastructure, as floating ip's adds flexibility to it.

You cannot add external network directly to instance. Use neutron routers to link private network to external networks and assign floating ip.

Hello, please confirm that your eth0 on Ubuntu 14.04 is in range of get output from ip netns exec qrouter-30d4b743-0a4e-4243-94d1-6e767e2f49d6 traceroute

2017-04-02 02:38:12 -0500 answered a question can not access floating ip

Hello, have you created and modified Neutron Routers ? Your privare network needs some way to communicate with external.

  1. neutron router-create RouterName
  2. neutron router-gateway-set PrivateNetwork ExternalNetwork
  3. neutron router-interface-add PrivateNetwork PrivateSubnet

If you done that check out what Neutron Namespace is telling you

  1. ip netns list
  2. neutron router-list
  3. ip netns exec qrouter-........ route (it supports standart tools such as ping, traceroute, iptables etc...)

It's best practise to convert VMDK to qcow2. Use qemu-tools for that. (Also availible on windows).

On linux it would be like 1. apt-get install qemu-utils 2. qemu-img convert -O qcow2 path-to-disk1.flat.vmdk path-to-output-disk1.qemu 3. glance image-create --disk-format qcow2 --file path-to-output-disk1.qemu --is-public False --name disk1 --container-format bare 3. or upload via GUI
