## #. The devtest scripts require access to the libvirt system URI.
##    If running against a different libvirt URI you may encounter errors.
##    Export ``LIBVIRT_DEFAULT_URI`` to prevent devtest using qemu:///system
##    Check that the default libvirt connection for your user is qemu:///system.
##    If it is not, set an environment variable to configure the connection.
##    This configuration is necessary for consistency, as later steps assume
##    qemu:///system is being used.

## #. The VMs created by devtest will use a virtio network device by
##    default. This can be overridden to use a different network driver for
##    interfaces instead, such as ``e1000`` if required.

## #. By default the node volumes will be created in a volume pool named
##    'default'. This variable can be to used to specify a custome volume
##    pool. This is useful in scenarios where the default volume pool cannot
##    accommodate the storage requirements of the nodes.

##    Note that this variable only changes the volume pool for the nodes.
##    Seed image will still end up in /var/lib/libvirt/images.
##    ::

## #. The tripleo-incubator tools must be available at
##    ``$TRIPLEO_ROOT/tripleo-incubator``. See the :doc:`devtest` documentation
##    which describes how to set that up correctly.
