Hello,
You will need to use a guest image that supports SLAAC and/or DHCPv6. As you can see from the message below, the DHCP failed because it was attempting to retrieve an address via IPv4. Also note that many cloud images only enable IPv4 by default, so you may need to create a custom image with IPv6 enabled for your testing. Alternatively, you could use config-drive to do early initialization of IPv6 network settings.

Subject: [Starlingx-discuss] How to enable IPv6 on stx-openstack?
Hi All,
I`m trying to deploy VM with IPv6 on stx-openstack, so I create the subnet by below command and I`ve tried both slaac and dhcpv6-stateful, but the VM didn`t get correct IPv6 address inside.
neutron subnet-create --tenant-id ${ADMINID} --name ${PUBLICSUBNET} --enable-dhcp --ip-version 6 --ipv6-ra-mode slaac --ipv6-address-mode slaac ${PUBLICNET} 2019::/64
I am able to see the IP on command show but VM actually doesn't gets correct IP.
controller-0:/home/sysadmin# openstack server list
