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...

Hi Punit,
it is ok since ovirt-engine is using loopback for its purposes, e.g. =
postgress databas access. Try to check netstat -putna | grep 127.0.0 to =
see how many things are attached to it.
If you are interested in checking what is going on a bit more have a =
look @ this great how-to =
