Hey there,
@Martin: I'm running Ubuntu 8.10, kernel 2.6.27-7-generic and the
virtual topology is the one described in
http://noxrepo.org/manual/vm_environment.html
yes, it is a virtual setup
regarding vdeslirp, you probably have a point there because I did
mess with it a bit in order to get openflow running. I got a buffer
overflow message from vdeslirp (i think it was when I run
start-vm-test, but I can't recall 100%), and I found this post
concerning a vde bug:
https://bugs.launchpad.net/ubuntu/+source/vde2/+bug/287109
I followed mariof's advice - downloaded the vde source and changed
slirpvde.c line:
static char pidfile_path[_POSIX_PATH_MAX];
to
static char pidfile_path[PATH_MAX];
and also added #define PATH_MAX 4096 in 3 other files that I got a
compile error, and recompiled vde. I did this kind of blindly, but it
did get openflow running.
Just now i tried to apt-get install vde2, but I still get the same
problem

Hi Kyrialos,
If you are using a virtual setup, check your vdeslirp.
