[Libguestfs] [PATCH 43 0/7] v2v: switch to ocaml-libvirt

[Pino Toscano]

Hi,

this series switches virt-2v to ocaml-libvirt, embedding the latest
version of it from git. This way, it is possible to improve the way
v2v connects to libvirt for both input, and output modules, and
interacts with libvirt (e.g. no more virsh calls needed in virt-v2v).

As side effect, virt-v2v now requires libvirt, as keeping it optional
would create too much burden.

I could not test all the libvirt input modes (like VDDK, and Xen), but
VMware and libvirtxml work fine as before.

Changes from v3:
- rebase on master
- update libvirt-ocaml from its master branch
- use $(srcdir) in common/mllibvirt/Makefile.am
- parse_libvirt_xml: open a libvirt connection only when needed (and
  only once)

Changes from v2:
- rebase on master

Changes from v1:
- rebase on master
- update ocaml-libvirt from libvirt-ocaml.git on libvirt.org, and adjust
  the code to it
- pass again the URI to input_libvirt_vddk, so an error message is
  preserved

Pino Toscano (7):
  v2v: require libvirt
  common: Bundle the libvirt-ocaml library for use by virt-v2v
  v2v: switch to ocaml-libvirt
  v2v: -o libvirt: use a Lazy for the connection
  v2v: -o libvirt: switch away from virsh
  v2v: test-harness: stop using the external ocaml-libvirt
  build: stop looking for ocaml-libvirt
