Hi Wodel, I think you need to fix DIB element files to build a guest image as CentOS Stream. Officially supported operating system in Trove is currently Ubuntu[1]. I am preparing Installation instructions Fedora/CentOS Stream users[2]  but that is not completed. You may not really need to build a guest image as CentOS Stream if you are a mysql or postgresql user, because Trove supports Docker Since Victoria. This means database service can runs as docker container inside the Trove instance. You can define the datastore image by using the "docker_image" config option[4]. --- [1]: https://docs.openstack.org/trove/latest/admin/building_guest_images.html [2]: https://storyboard.openstack.org/#!/story/2009918 [3]: https://opendev.org/openstack/trove/src/branch/master/integration/scripts/fi...

This is the command I used to build the image :  ./trovestack build-image ubuntu bionic true ubuntu /home/stack/trove-xena-guest-ubuntu-bionic-dev.qcow2 My OS is a Centos 8 Stream. you can find the whole log of the operation attached. Thanks in advance. Regards.
