Public bug reported: It's a known issue that metadata services don't work for ipv6-only tenant networks [1]
However, it can be possible that operators want to use ipv4 and ipv6 tenant networks with an underlay ipv6 infra. This doesn't work as you can see in the devstack failure [2] because the metadata agent, when building the request, doesn't check if the nova_metadata_host is an ipv6 address to add the corresponding square brackets [3].
