How to use kvm in a Centos 6 docker container via docker machine

I'm trying to use kvm in a Centos 6 docker container, via docker machine. My docker machine vm (vmware fusion based) supports nested VMs, but in my docker container I'm seeing:

modprobe kvm
FATAL: Could not load /lib/modules/4.1.12-boot2docker/modules.dep: No such file or directory
modprobe kvm_intel
FATAL: Could not load /lib/modules/4.1.12-boot2docker/modules.dep: No such file or directory

Any idea what I'm missing?

You can use KVM simple container in DockerHub. Source code is available on GitHub and has been tested in DockerHosts with Ubuntu 16.04, Centos 7, Centos-Atomic 7.2 and RancherOS.

you may need to load the kvm and kvm_intel module on the docker host before trying to run the container

Docker isn't virtual machine. It is a way to package your application.

So I think that running KVM - Kernel Virtual Machine it is not possible inside docker container.

You can read about difference between Docker and other kind of virtualization on page: https://www.docker.com/what-docker
