Provide an ‘index’ (or ‘index.asc’) file somewhere on a publib webserver. For examples see: http://download.opensuse.org/repositories/Virtualization:/virt-builder-im... http://builder.libguestfs.org/index.asc You will also need to create a GPG key to sign the index file. Provide both the GPG *public* key and the location of the index file to virt-builder, usually in the /etc/virt-builder/repos.d/ directory or (for a single user) in $HOME/.config/virt-builder/repos.d/ in this format: $ cat /etc/virt-builder/repos.d/opensuse.conf [opensuse.org] uri=http://download.opensuse.org/repositories/Virtualization:/virt-builde... gpgkey=file:///etc/virt-builder/repos.d/opensuse.gpg If you want virt-builder upstream to ship your repo file and public key then that's totally fine. Submit a patch to add that to the builder/ subdirectory, as opensuse has done (see builder/opensuse.conf.in, builder/opensuse.gpg and there are some small Makefile changes too). On the other hand you may prefer to ship these files separately, but then packaging that becomes your problem. Having it in upstream virt-builder will mean it is available to all users out of the box on every Linux distro. There are various tools now available to create and manage index files, including virt-builder-repository (written by Cédric CC'd) and virt-index-validate (written by myself and Pino also CC'd).
