I tried it against two vCenter instances, and I see the additional XML
like this:

  <domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
  ...
    <vmware:datacenterpath>Folder/Datacenter</vmware:datacenterpath>
  </domain>

That seems fine and it's something we can use in libguestfs.

Looks good to me, so ACK.

Minor comment on the patch below.

This appears to be an unrelated fix?  Perhaps it should go in a
separate commit.
