Would users really want that translation done automatically? I'd rather be told how to do it myself so I can check the outcome; but maybe I'm a bit strange that way. :-) In theory it seems like someone who knew what they were doing with python should be able to rip out the sxp parsing stuff from xend, and then once you had a structure with all the configuration in it, write that out into a .cfg file. I'm sure that would be a useful tool to have in-tree, particularly if we manage to actually get rid of xend this release cycle. -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
