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.<div><br></div><div>BR/Krish</div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Dec 6, 2016 at 8:18 PM, Rami Rosen <span dir="ltr"><<a href="mailto:roszenrami@gmail.com" target="_blank">roszenrami@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Eri,<br>
The driver is the veth driver, but it should be loaded automatically<br>
when running this<br>
command.<br>
<br>
What do you get when running:<br>
<br>
modprobe veth<br>
<br>
And what do you have when running<br>
lsmod | grep veth ?<br>
<br>
Which kernel are you working with ? can you paste the output of<br>
"uname -a"? is it a kernel you built from source, or a kernel which is<br>
part of a distro?<br>
<br>
