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

then 

$ 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 
10.0.0.2:80 (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

<https://github.com/mirage/ocaml-openflow>
        developed with mirage, for the ICC paper

<https://github.com/frenetic-lang/ocaml-openflow>
        possibly more complete and actively developed, not checked

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