I don't know your container configuration but if you use the device 
white list, you must ensure you have the right to create /dev/net/tun.

I just tried tunctl, and that nicely crashed my host. My kernel is a 
2.6.32-24-generic. I suspect a problem with sysfs, so at the first 
glance I recommand to try with a 2.6.35 kernel.
