Thanks Rami for all the help. Yes lsmod shows that veth is not there.
Perhaps the kernel has not been compiled with config_veth option enable in
.config. Exact kernel version I will let you know tomorrow but most of the
chances its 4.* kernel. Its customized kernel I got from different team,
they have build it via yocto and I had to setup one network topology on it.

Hi Eri,
The driver is the veth driver, but it should be loaded automatically
when running this
command.

What do you get when running:

modprobe veth

And what do you have when running
lsmod | grep veth ?

Which kernel are you working with ? can you paste the output of
"uname -a"? is it a kernel you built from source, or a kernel which is
part of a distro?
