Hi Er, First, the veth modules should be in your kernel, as it does exist in 3.14: http://lxr.free-electrons.com/source/drivers/net/veth.c?v=3.14 It could be that the iprotue1 package you have does not support veth. What does the version of iproute2 you have on your machine ? what is the output of "ip -V"? Also do you have man page of "ip link" ? and in case you have, please run "man ip link" and post here what you see in the "TYPE :=" section, you have veth, Also, assuming you have access to the source tree where the kernel was built, what do you get when running, from the root of this tree: more .config | grep VETH And finally - which distro is running on this device ?
