In the mapped security model, VirtFS server intercepts and maps the file object create and get/set attribute requests. Files on the fileserver will be created with VirtFS servers (QEMU) user credentials and the client-users credentials are stored in extended attributes. On the request to get attributes, server extracts the client-users credentials from extended attributes and sends them to the client.
