Loopback interface has huge network transctions
Hi, I have noticed that the loop back interface has huge network packets sent and received...is it common or need to some tweaks.... 1. Ovirt 3.5.1 2. Before ovirt engine installation...loop back address doesn't has that huge amount of packets sent/receive.... 3. After Ovirt engine install it's keep increasing.....and in just 48 hours it reach to 35 GB...
