hi,
niceee!

first of all, to have a better console experience, try the following: stty raw -echo 
< /dev/tty && java -jar .....

then to have the 2nd interface just do the following to the console:

conf t
int sdn2
 macaddr <copy-from-hypervisor>
 exit
serv p4 p4
 export-port sdn2 1
end
wr

also to silence the console, remove the "line tty1" from -hw.txt

br,
cs
