Shuttleworth: Losing graciously

The term "virtual machine" is usually reserved for kvm and suchlike, i.e. virtualization that emulates hardware. In such vm setups systemd on vms knows nothing of systemd on the host.

If your are refering to container virtualization (i.e. multiple userspaces on the same kernel) then yes, the idea is that the systemd in the container cooperates friendly with the host's systemd when it is interested in cgroups.
