There are a number of pre-defined scenarios included in ACRN's source code. They
all build upon the three fundamental modes of operation that have been explained
above, i.e. the *logical partitioning*, *sharing*, and *hybrid* modes. They
further specify the number of VMs that can be run, their attributes and the
resources they have access to, either shared with other VMs or exclusively.
The predefined scenarios are in the `misc/vm_configs/scenarios
<https://github.com/projectacrn/acrn-hypervisor/tree/master/misc/vm_configs/scenarios>`_
folder in the source code. XML examples for some platforms can also be found under
`misc/vm_configs/xmls/config-xmls <https://github.com/projectacrn/acrn-hypervisor/tree/master/misc/vm_configs/xmls/config-xmls/>`_.
The :ref:`acrn_configuration_tool` tutorial explains how to use the ACRN
Configuration tool to create your own scenario or modify an existing one.
