  okay, then there is enough places where we must tweak the code depending
on the version of Xend running, this makes the code harder, less maintainable,
so unless we actually get a problem by still adding this unecessary extra
data, I think it is better to keep the code simpler. I just added a comment
to log that information in the code:

    if (ip != NULL)
        virBufferVSprintf(buf, "(ip '%s')", ip);
    /* apparently not needed any more for xen >= 3.1 but harmless */
    if (hvm)
        virBufferAdd(buf, "(type ioemu)", 12);

  thanks,

Daniel
