Hi Team,Julia,

@Julia Thank you for the response.
>>Additionally is this UEFI mode or Legacy BIOS mode?
We are using UEFI.

We tried introspection for two nodes from the undercloud node. Te following is our observation:
1. Undercloud is assigning an IPV6 IP to the node.

The PXE boot Failed with the following error:
PXE-E99: Unexpected network error.

On further debuging this issue, We found that a container: ironic_pxe_tftp is in unhealthy state. But this container should be running.
On checking the logs, we  found the following:
"
[root@undercloud-ete log]# podman logs 356715c49cd4

dnsmasq: bad command line options: try --help

dnsmasq: bad command line options: try --help

dnsmasq: bad command line options: try --help

"
We had previously raised this issue in 2022 as well:
https://lists.openstack.org/pipermail/openstack-discuss/2022-June/029062.html

For this a bug was raised which was fixed
https://bugs.launchpad.net/tripleo/+bug/1978892

We cross-verified, and the changes are present on our undercloud. But still we are unable to start the ironic_pxe_tftp container.

Could you please help us with this?

Thanks and Regards

Hi Team,

We were trying to perform IPV6-based deployment of TripleO.
We are following the link:
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.0/html/bare_metal_provisioning/sect-deploy#sect-example-templates

 

Try following the more recent documents, specifically OSP16.1 or 16.2. 

As per our environment, we set the "ipv6_address_mode" to "dhcpv6-stateful" and tried undercloud deployment. It was successful.

 

Good, that is required for IPv6 PXE. 

But when we try node introspection, openstack is not providing an IP that will be used for PXE booting the system. We have enabled PXE booting on the IPV6 network.
On Dell machines, we get the following error:
"PXE-E16: No offer received."

I suspect we will need to see the configuration. Paste.opendev.org?

For your reference, the undercloud file which we used is attached.
We also tried to find the communication happening on the br-ctlplane interface when the machine tries to boot over IPV6 PXE boot. I am attaching those tcpdump records as well. We are unable to find the MAC address of our machines.

I suspect this might be in the territory of the hardware, while being set for IPv6 network booting, maybe the configuration needs to be checked/reasserted on the interface level. It sounds as if it is using a different interface.

 

Not seeing the expected MAC addresses is rather suspect in this case, although PXE with v6 is a little different pattern wise. Have you tried mirroring the port your expecting to see traffic cross from the physical machine to see if it is seeing the announcements and issuing the DHCPv6 packets required?

Additionally is this UEFI mode or Legacy BIOS mode?

Questions:
1. Is it even possible to perform tripleO deployment with IPV6?
2. Do we need to do some extra settings, so that our baremetal machines can be PXE booted?

Thanks and Regards
