To reproduce, just restart the network service when there's an instance running - the IPv6 address appears to get added to the bridge when you first start an instance deleting the IPv6 address with e.g. $> ip addr del fe80::fc16:3eff:fe1d:632/64 dev br0 allows the network service to start again Upstream bug is: https://bugs.launchpad.net/nova/+bug/853892 Should be fixed in diablo by: a) removing --interface= from the dnsmasq flags because of this: http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2011q3/005247.html b) fixing the ordering of IP address on the bridge so that dnsmasq actually sees the requests https://code.launchpad.net/~vishvananda/nova/new-dnsmasq/+merge/76096 https://code.launchpad.net/~vishvananda/nova/fix-dhcp-ms/+merge/76361 openstack-nova-2011.3-1.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/openstack-nova-2011.3-1.fc16 Package openstack-nova-2011.3-1.fc16: * should fix your issue, * was pushed to the Fedora 16 testing repository, * should be available at your local mirror within two days.
