Could not initialize SDL(No available video device) - exiting
Notes
=====
- The error message: it is probably not a big deal - can make them not being blocking by modifying https://github.com/CIRCL/Circlean/blob/master/tests/run.exp#L10
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760365
- Could not initialize SDL(No available video device) - exiting < = this one is blocking
- I guess it is the vnc switch - requires x11 installed
- If you use a cloud instance, you will need to get qemu to open a port you can connect to with vnc
- The good thing of having VNC is that you can see what explodes when you're running the image
