The following is just from the Coverity check... I don't have all the
build environments that have proved to be problematic over the last week
or so...
I assume all you've done is take the generated code and use that rather
than going through the problems as a result of attempting to generate
the code.

Will this allocate anything into libxldisk? That will eventually be
cleared out by the libxl_device_disk_init() on the next pass? I note
numberous strdup's of libxkdisk->* fields, so I am assuming that there's
been an allocation, although I suppose it could use pointers to

Coverity notes that libxldisk is leaked here especially if list == NULL
(or list->type != VIR_CONF_LIST). Although I assume by inspection that
it'll be leaked whether the list finds something or not.

I would think the libxldisk needs to be addressed here as well although

Coverity complains that 'diskVal' going out of scope leaks what it
points to - especially if "diskVal->list != NULL" takes the false branch
above.
This is something I pointed out in patch 5 of 6 in my Coverity series:
http://www.redhat.com/archives/libvir-list/2015-January/msg00251.html
Seems there should be a virConfFreeValue(diskVal) or VIR_FREE(diskVal)
here and...
