Xen project Mailing List

Thanks a lot, Thomas, Mindy, for the quick help!

i made progress up to "mirage configure --xen", which failed because of gtk issues (triage in progress). Am on Ubuntu 14.04, tried a couple of workarounds (like http://www.linuxquestions.org/questions/linux-newbie-8/xdot-library-is-not-able-to-open-graphs-in-ubuntu-14-04-a-4175504761/).

Out of curiosity, is there a preferred distro for dev/testing?

Thanks!

madhuri.

In your git clone directory, do:

Â opam pin add -k git mirage-net-xen .

This will build and install your version of the library. Then "make
clean" in your test unikernel and rebuild.
