The use of IPv6 is not supported on the provisioning network: See support matrix table in doc[1]: "Provisioning (PXE/DHCP)" - "Interfaces on this network are IPv4 only." I am closing this bug as a dupicate of RHBZ#1459187 - [RFE] ability to deploy overcloud using a IPv6 provisioning network [1] https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/html-single/ipv6_networking_for_the_overcloud/index#using_ipv6_in_red_hat_openstack_platform *** This bug has been marked as a duplicate of bug 1459187 ***
