Hello again! Thanks everyone for joining the discussion and for the advice, much appreciated. To summarize the current situation: - at the moment it's not possible to build any rpm-based image on ubuntu focal using diskimage-builder with the centos-minimal element; - so far, we've successfully built the centos8 based ipa-ramdisk using diskimage-builder in ironic-python-agent-builder on centos-8 nodeset, but using the same nodeset also for testing the image (so running devstack) would be very time expensive because of the changes involved; - during the last ironic meeting, it has been decided to switch to the centos element and give that a try using the ubuntu focal nodeset; main concern about this approach is the final size of the ipa ramdisk, tests are ongoing and it looks promising: https://review.opendev.org/757808 https://review.opendev.org/757811 https://review.opendev.org/757812 Thanks again!

Uhm, maybe unattended virt-install could help there?
I expect that would be almost unworkable from within a virtual machine instance without nested virt acceleration. -- Jeremy Stanley
