Hi Thomas,

here's some useful information here:

https://www.somerandomidiot.com seems to have shut down. (i was half
way through the instructions around a week ago, tried to access it
today, but couldn't). Is there any other alternate you would recommend
for test environment setup? i've made first pass at necessary changes
in mirage-net-xen's frontend.ml
and would love to run a test once before fixing log levels. Apologies
for the delay in getting this done!

Oh no! somerandomidiot.com seems to be in an inconsistent state, sometimes able to serve pages and sometimes not. I'll send you the content directly off-list.

somerandomidiot.com is built with `mirage-seal` -- perhaps some logging there would be helpful. :)

Great, thanks for the quick response! i assume below advice still holds
true, in that case.

You could start by cloning the mirage-skeleton repository and making a
new example based on "console" that uses logging rather than printing.

For modifying libraries, you'll need to know how to "opam pin" a
modified package for testing. There's some useful information here:


(however, I find it easier to look in the Makefile to find the
dependencies, rather than reading the source of the mirage tool, and
make sure you do "opam pin -k git" to pin in "mixed mode", or you'll
have endless trouble with stale OASIS files)

i can start with
, as listed in the Pioneer Projects page.

Is there a recommended regression test set? i looked around
https://mirage.io/wiki/contributing, but couldn't find any pointers.
There are no automated tests. Running mirage-skeleton would let you
check if it was working.

Dave Scott made a branch that allowed mirage-net-xen to run on Unix
(by making the Xen stuff abstract), which allowed running unit-tests
easily. I think it needs a bit of work to rebase it on master, though:


(many of the changes on this branch have already been merged)

Some proper integration tests that spin up multiple Xen VMs would be
great too. I know this has been discussed a few times, but I'm not
sure what the status is.

Thanks a lot!

i am interested in contributing to MirageOS (during non-work hours), and
wondering if there is a beginner project recommendation? This would be
first project in OCAML (have 15 years industry coding experience in C
(Oracle Database Server, VMware ESX) and C++ (VMware vCenter), and
recent 9
months in Python (Flocker)).

Looking through
https://github.com/mirage/mirage-www/wiki/Pioneer-Projects ,
i understand Logging is taken from recent emails on this mailing list.
there is any other beginner-friendly project that i could take up?

Thanks a lot!
Hi Madhuri,

There are lots of libraries that need improved logging, so as long as
people say which ones they're working on there should be no problem -
it would be great if you want to work on that!
