The idea is to integrate LXD into OpenStack as a "lightweight VM". So, LXD runs a system with a full init system and executes them inside of a Linux Container.

The idea is to integrate LXD into OpenStack as a "lightweight VM". So, LXD runs a system with a full init system and executes them inside of a Linux Container. Another term for this is a "system container". Kubernetes is designed for running Application Container images (e.g. docker, oci, appc) and in this case those containers are running not as Linux containers on a shared Kernel but inside of a VM with Xen/Hypernetes. Another implementation of this "app container in a VM" concept is Clear Containers which is available in rkt[1] and can, like Hyper, run the application container image formats (docker/appc). This is all a bit confusing so let me know if this helps :) [1] https://coreos.com/blog/rkt-0.8-with-new-vm-support/ https://coreos.com/blog/rkt-0.8-with-new-vm-support/
