VMs are a completely different beast, as they emulate the real hardware and are used as such.

Docker containers were used completely differently from the start. For example, for a long time it had not been possible to run a shell inside an already running container.

Er, no. If you had a current version of the util-linux package you had nsenter. For docker containers they finally made an exec command, but nsenter always worked.

Well, nsenter had not been a documented way to enter a running container until the most recent Docker. And it's still discouraged.
