reg_linux_diskfull_installation_flat fails on ubuntu-22-ppc64le-devel and ubuntu-24-ppc64le-devel in build #121 of xcat-core-devel-ubuntu-cd. The node answers ping but the case ends on "root@xcat25-cn: Permission denied (publickey,password)" and the node status never leaves powering-on. The serial console shows why: the Subiquity installer starts, runs the early-commands, errors, tars /var/log/installer to port 8080 and reboots. Nine cycles in 75 minutes. The installed system never exists, so the address belongs to the live installer and it refuses the root key. Two causes, both POWER-only. mkinstall picks pre.ubuntu.subiquity, then overwrites that choice with pre.ubuntu.ppc64 for every ppc64 node. That script writes a partman recipe; the early-commands append it to /autoinstall.yaml, which Subiquity then cannot parse. pre.ubuntu.subiquity has a UEFI branch and a BIOS branch and nothing else, so a ppc64el node takes the BIOS branch and is given a bios_grub partition. POWER firmware boots from a PReP partition. debian_install_prescript.t drives the script choice, which mkinstall keeps inline, so it bails out. ubuntu_subiquity_storage.t gains a PReP case; its extracted block asks uname for the machine architecture, which the block does not do yet.

xCAT
xCAT is a toolkit for deployment and administration of clusters of all sizes.
The xCAT sunset was only a quick eclipse
Dear xCAT Community,
The xCAT sunset has changed course. VersatusHPC has been invited to join the xCAT Consortium, and future development will move toward direct upstream contributions coordinated with the Consortium and its existing member companies.
That matters most for Enterprise Linux 10 (EL10). EL10 support is coming to xCAT, restoring a future operating-system path for sites that still rely on xCAT. This is an important change from the previous sunset guidance, where the lack of an EL10 path was one of the strongest reasons to move away from xCAT.
The xCAT Consortium continues to recommend Confluent as the long-term successor to xCAT, and that remains the Consortium position. Users planning new cluster-management deployments should evaluate Confluent and its xCAT comparison documentation.
At the same time, xCAT is no longer sunsetted. The Consortium and participating companies will continue updating xCAT while there is community and user demand for it.
In summary:
- xCAT development is continuing upstream through the Consortium and participating companies.
- Enterprise Linux 10 support is coming.
- Confluent remains the Consortium-recommended successor and migration path.
- xCAT updates will continue while there is community and user demand.
We want to thank the xCAT Consortium and community for keeping this project moving. The sun went behind the moon for a moment, but xCAT is still here.
For more information on Confluent and how to get started, please visit the Confluent: Project Page, Documentation or Confluent vs xCAT comparison.
With thanks,
The xCAT Consortium
