No, this is virtualization - vmm/vmd is a legit HVM.

So it is better than systemd :p

it's really not comparable. SystemD is an init system (and you're conflating systemd with CGroups in Linux, which would be part of the kernel and not related to systemd at all) and a Hypervisor.

More comparable comparisons could be: bhyve for FreeBSD, xhyve for OSX, virtualbox for... everything. Or QEMU/KVM on Linux.

Oh man, I did not mean to type systemd! I ment docker.

Aha, that makes sense.

But still. Docker is containers, vmm is full virtualisation.

Docker can be compared to FreeBSD jails, Solaris Zones or.. actually, cgroups in linux (for masochists).

I know I know. It was a joke and a slight jab at docker :p

The Urban Dictionary also defines docker as someone who makes a slight jab.
