This series is a second attempt to add a mode of virt-v2v operation where it leaves the config and disk image conversion, rollback on errors, registering with the destination hypervisor, etc. to a third-party toolset, and performs only tuning of the guest OS to run in the KVM-based hypervisor. The first 14 patches are just refactoring and rearrangement of the code, factoring the implementation

Per my previous email: https://www.redhat.com/archives/libguestfs/2017-September/msg00203.html I'd like to talk about requiring a more modern version of the OCaml compiler. These commits show some of the code changes which would be possible with OCaml >= 3.12 [which it turns out we already require by accident] and also with OCaml >= 4.02. The latter is my favoured option. Rich.
