Basically, this is triggered by the following: $ virt-builder fedora-22 --install <whatever> gnupg2 (used to import keys the first time when installing packages from a repository) requires the use of an agent, thus spawning gnupg-agent which holds /sysroot/dev, which cannot be unmounted. It seems that this issue has been fixed in recent versions of gnupg2/rpm/dnf, so updating before installing anything: $ virt-builder fedora-22 --update --install <whatever> which should then work (at least it does for me). Rich, if this fixes the problem for you as well, would it be possible to update the fedora-22 templates with newer versions of packages?
