I'm trying this on virtual machine with ubuntu 14.04, compiled `pfcount` and run, here's the output:\r\n```\r\nvagrant@ubuntu-1404:~/PF_RING/userland/examples [13:15:10][dev] $ sudo ./pfcount -i lo\r\npfring_open error [No such device] (pf_ring not loaded or interface lo is down ?)\r\nvagrant@ubuntu-1404:~/PF_RING/userland/examples [13:15:31][dev] $ sudo ./pfcount -i eth0\r\nUsing PF_RING v.6.7.0\r\nCapturing from eth0 [mac: 08:00:27:AD:41:5D][if_index: 2][speed: 1000Mb/s]\r\n# Device RX channels: 1\r\n# Polling threads:    1\r\nDumping statistics on /proc/net/pf_ring/stats/2852-eth0.16\r\n=========================\r\nAbsolute Stats: [1 pkts total][0 pkts dropped][0.0% dropped]\r\n[1 pkts rcvd][84 bytes rcvd]\r\n=========================\r\n...\r\n```\r\nIt clearly shows that the interface `lo` is not recognized while `eth0` works fine. What am I missing? Thanks!"}}
