NAME

       virt-v2v-hacking -

DESCRIPTION

       First a little history.  Virt-v2v has been through at least two complete rewrites, so this
       is probably about the third version (but we don't intend to rewrite it again).  The
       previous version was written in Perl and can be found here:
       https://git.fedorahosted.org/git/virt-v2v.git

       The current version started out as almost a line-for-line rewrite of the Perl code in
       OCaml + C, and it still has a fairly similar structure.  Therefore if there are details of
       this code that you don't understand (especially in the details of guest conversion),
       checking the Perl code may help.

       The files to start with when reading this code are:

       •   types.mliv2v.ml

       types.mli defines all the structures used and passed around when communicating between
       different bits of the program.  v2v.ml controls how the program runs in stages.

       After studying those files, you may want to branch out into the input modules (input_*),
       the output modules (output_*) or the conversion modules (convert_*).  The input and output
       modules define -i and -o options (see the manual).  The conversion modules define what
       guest types we can handle and the detailed steps involved in converting them.

       Every other file in this directory is a support module / library of some sort.  Some code
       is written in C, especially where we want to use an external C library such as libxml2.
