I had to switch my development system back to Gentoo (Calculate Linux) from Debian. I used to run Debian 6, but it didn't come with a current (read: non-buggy) version of libvirt. Unfortunately, Debian 7 doesn't contain a package for ghdl, so I was pretty much out of luck. I've been happy in the past with Gentoo and variants, so I decided to give Calculate a shot, and after a long day of fiddling I have it installed, its kernel configured properly for lxc and libvirt, and all of my Controlix development environment up and running. The libvirt bug is gone, and although I had a similar wierd crash-on-init bug with Ncurses pop up, I was able to switch back to the old libc-based console I/O routines. Everything is now building and running without errors, yay! All fixes have been committed.
