Regarding your question about the changes to the VMware driver: The
only required change is the addition for "ctx.datacenterPath = NULL"
where virVMXParseConfig is called. The other additions are not really
necessary. I made them for the sake of completeness and to match the
usage in the ESX driver.

Overall I'm happy with this patch. The only concern I have is that the
domain XML might not be quite the right place to expose this
information. But there are not many other places to expose this
without adding new public API. But I assume that the domain XML is the
most convenient was for libguestfs to get this information, isn't it?

Anyway, there is no later version of this patch. I'm okay with you
pushing it to the libvirt repo.
