Right now, if the VIPs have IPv6 listed first in the list of addresses, but the network fields like machineNetwork, clusterNetwork or serviceNetwork contains IPv4 primary address, the installation would progress and the bootstrap would end failing.
A validation needs to be included to ensure all required fields are IPv6 primary.
Change would likely be implemented here https://github.com/openshift/installer/blob/master/pkg/types/validation/installconfig.go#L241
[OSASINFRA-3238] Installer: ensure all network fields has IPv6 primary CIDRs when VIPs contain IPv6 primay addresses
metadata:

This is an example of a portion of install-config.yaml file that would cause an issue and we want to avoid reaching that point. This would make the nodes to have IPv4 first instead of IPv6:
status: addresses: - address: 10.0.3.125 type: InternalIP - address: fd2e:6f44:5dd8:c956::1e5 type: InternalIP - address: ostest-rszhf-worker-0-bgtm9 type: Hostname
This change is still valid, but it did have much traction. This is a really low prio effort.
mdemaced . Please, can you add an update, or what is the current status of it.
To create a dual-stack cluster you can follow this doc:
https://docs.openshift.com/container-platform/4.17/installing/installing_openstack/installing-openstack-installer-custom.html#install-osp-deploy-dualstack_installing-openstack-installer-custom
There is another doc:
https://github.com/openshift/installer/blob/main/docs/user/openstack/deploy_dual_stack_cluster.md (In the network section do not follow the steps proposed because it uses a provider network, just create a basic tenant network). Feel free to ask me more details about it.
