Hi,
So I am having problem running docker image. When I run command: *docker run hello-world* , this is the output:
> 
> 
> docker: Error response from daemon: failed to create endpoint
> elastic_hypatia on network bridge: failed to add the host (vethf9c4250)
> <=> sandbox (vethc439d7e) pair interfaces: operation not supported.
> ERRO[0000] error waiting for container: context canceled
> 

So I suspect that the veth module is missing and as checking, I ran the check-config.sh script, and here is what I get

Even running *modprobe veth* showing that veth is not there:

After going around the internet, I found out that somebody had the same issue with me: https://marc.info/?l=openembedded-devel&m=154773496216135&w=2 , and they also think that veth missing is the problem. And as suggestion, I added in my local.conf:
CORE_IMAGE_EXTRA_INSTALL += "kernel-modules docker"
But they also mentioned the actual solution is :
I found the issue.  The veth kernel parameter was not enabled.  Once I added
CONFIG_VETH=y to my docker.cfg file, I was able to successfully run a
docker container in my openembedded OS So where could I do the same? I've used the rocko version and it doesn't have the linux/docker.cfg file? Or could I can create one by myself?
