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.
