Public bug reported: When running an instance on a network with ipv6-address-mode dhcpv6-stateful, the instance fails to receive responses from the DHCP server. The workaround is to add an explicit security group rule allowing
--proto udp --dst-port 546 --ethertype IPv6 and then the DHCP handshake succeeds successfully. See https://review.openstack.org/#/c/386525/ and the failures at e.g. http://logs.openstack.org/25/386525/8/check/gate-tempest-dsvm-neutron- full-ssh/b4c7bf0/, the same setup worked fine in December, so this seems to be a regression introduced since then. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
