Description of problem: I followed the following documentation to deploy an allinone instance of Kilo: https://www.rdoproject.org/Neutron_with_existing_external_network No errors were present during the deployment and it reports the status as OK. I then started an instance of Cirros. The instance starts correctly and I see a floating IP assigned. I then go into the console and view the output of 'ifconfig' for the cirrus instance. It is assigned a ipv6 address and no the floating address. Under /var/log/messages of the CirrOS node I also see 'no IPv6 routers present' I also found: avahi-daemon[745]: Registering new address record for fe80::fc16:3eff:fe80:c58 on tapb179fe4e-b8.*. This all happens despite having use_ipv6=false set in /etc/nova/nova.conf. I also restarted the whole node to insure it was set. More details can be seen on ask.openstack: https://ask.openstack.org/en/question/67724/kilo-assigning-ipv6-even-though-its-disabled/ Version-Release number of selected component (if applicable): CentOS 7 - 3.10.0-229.4.2.el7.x86_64 openstack-packstack-2015.1-0.1.dev1537.gba5183c.el7.noarch How reproducible: Follow the installation guide on the RDO site and then view a cirros instance on the console. Steps to Reproduce: 1. Deploy RDO following the steps outlined here https://www.rdoproject.org/Neutron_with_existing_external_network 2. Insure ipv6 is disabled 'use_ipv6=false' 3. Start a cirrus instance, which should be automatically assigned a floating address (ipv4) 4. Open a vnc console to the cirrus instance and check the IP assignment using 'ifconfig' 5. Check dmesg or /var/log/messages for ipv6 messages (as above) Actual results: The cirros instance is assigned an ipv6 address, even though ipv6 is disabled, and no ipv6 router is present. Expected results: The cirros instance should be assigned an ipv4 address Additional info: Available on request
