# TODO: Consider converting to ansible virt module.

# NOTE(cinerama) openSUSE Tumbleweed & Leap have different distribution
# IDs which are not currently accounted for in Ansible, so adjust facts
# so we can have shared defaults for the whole SuSE family.
# This change can be removed when the pull request at
# https://github.com/ansible/ansible/pull/17575 lands in a new version.
