> Containers are not isolated Operating Systems: Docker containers share the host kernel. This is what makes them lightweight and great for single services. Whereas desktop environments expect system services like (systemd, logind, udev, DBus) and device access to be available. Containers don’t provide that by default.

I thought Docker images always run in a VM on non Linux systems, no? This guy is running Windows on host, right? Confusing

They are talking just about what's in the container there, not the whole stack.
