Configuration by an XML config file is obsolete. You can use it only in stable 0.6.X version of coLinux. The version 0.7.1 informs you: XML configuration files are obsolete. Please pass command line options, or use '@' to pass a command-line compatible configuration file (e.g. @config.txt) The complete list of all entries for the new format is installed as file colinux-daemon.txt in your coLinux installation. A converter from XML to CFG is available as xml2cfg-0.1.0.zip on SF or here
