Indeed, it looks like it has a problem opening the netfilter-conntrack  
socket. Could you try using the userspace conntrack tool, for example  
performing "sudo conntrack -L" to list the connection tracking  
entries? Perhaps some modules are not installed automatically.

Also, I'm not entirely sure if you should be running the relay inside  
a virtual machine. For testing purposes it should be fine, but  
realtime media traffic probably does not flow well through a  
virtualized host.
