the different targets for the mirage libraries conflict and can't be installed 
simultaneously in the same opam compiler switch.

the way that i deal with this is to have multiple compiler switches with the 
different mirage packages installed. i tried to explain this at the end of 
<http://openmirage.org/wiki/install> but now realise that it doesn't flow into 
<http://openmirage.org/wiki/mirage-www> as neatly as it might. i'll try and fix 
the install instructions so that it does!

basically-- the current compiler switch you're using has the mirage-xen package 
installed which conflicts with the mirage-unix packages (mirage-net-socket in 
this case). just "opam remove" the conflicting packages. in your case probably

$ opam remove mirage-xen


$ make unix-socket-build
$ make unix-socket-run

...should work, giving you a running instance of the openmirage website at 
localhost:80 (or whatever port number is currently specified in ./src/www.conf).

using multiple compiler switches to manage this is pretty straightforward: to 
build using the mirage network stack:

$ opam switch 4.00.1+mirage -a 4.00.1
$ eval $(opam config env)
$ make clean
$ make unix-direct-build
$ make unix-direct-run

...which should give you a running instance of openmirage website at (or specified port number as above).

then finally to build a xen vm:

$ opam switch 4.00.1+xen -a 4.00.1
$ eval $(opam config env)
$ make clean
$ make xen-build
$ make xen-run ## if appropriate :)

...which should result in openmirage website in a running vm.

there are a couple of ocaml openflow bindings

        developed with mirage, for the ICC paper

        possibly more complete and actively developed, not checked

haris or anil probably know more about current status of these...
