[elbe-devel] [PATCH] dockerfile: make elbe-testing run in docker
Manuel Traut

Thu Jul 12 16:10:12 CEST 2018
a running libvirtd is needed in the container for elbe-testing
this also drops ssh inside the container, because it should be
ok, to just attach a bash to the container.
also the hard coded kvm-gids are replaced by a solution that
should work on all distros.
