When the first installation,I follow the README.
cd p4factory/targets/basic_routing/ make bm sudo ./behavioral-model
It is successful.
But today,I want to do the same thing,use these code
sudo ./behavioral-mode
error
`wpq@wpq-VirtualBox:~/p4factory/targets/basic_routing$ sudo ./behavioral-model
No PD RPC server address specified, using 127.0.0.1:9090
No listener specified, switch will run in standalone mode

P4 Program: basic_routing

Starting RPC server on port 9090
bmi_port_interface_add(port_mgr, veth_name, n_veth, pcap_filename): ERROR -1 at main.c:434wpq@wpq-VirtualBox:~/p4factory/targets/basic_routing$
`

Every time you restart your machine, you need to create the veth interfaces again using the script under tools. Otherwise you get the error you are seeing because the switch cannot connect to any interface.
