'virt-ctrl' (originally called 'mlvirtmanager') is a reimplementation
of virt-manager in OCaml.  It is not feature-complete by any means,
but does allow you to show the running domains and start and stop
defined domains.  The main functionality _missing_ is the ability to
define new virtual machines, change the resources allocated to
domains, or show the machine console.


Building
----------------------------------------------------------------------

  ./configure           # Checks that you have all the required bits.

  make all		# Builds the bytecode version of libs/programs.
  make opt		# Builds the native code version of libs/programs.

  make install          # Install in OCaml directory, and the binaries
       			# in $prefix/bin.

Then have a look at the program 'virt-ctrl.opt'.


Windows
----------------------------------------------------------------------

I have built libvirt (the bindings), examples, mlvirsh and virt-ctrl
on Windows using the MinGW port of OCaml.  It's quite likely that it
will also work under VC++, but I have not tested this.

You should make sure that your $PATH (environment variable) contains
the names of the directories containing all required DLLs, in
particular you will require:

  libvirt-*.dll		(from libvirt)
  libgnutls-*.dll	(from GnuTLS)
  libgcrypt-*.dll
  libgpg-error-*.dll
  libtasn1-*.dll
  libxdr.dll		(from libxdr)
  libxml2-*.dll		(from libxml2)
  and, a multitude of DLLs from GTK if you want to run virt-ctrl

You can use a tool such as Dependency Walker to find/check the
locations of dependent libraries.

To build the Windows installer, you will need NSIS.  Then do:

  ./configure --with-nsis=/c/Progra~1/NSIS
  make all opt
  make wininstaller

This should build a Windows binary installer called
ocaml-libvirt-$VERSION.exe which includes the bindings, all required
DLLs and all programs that can be built under Windows.
