Do you have any MACs in effect?

Does the host use cgroupsv2 or cgroupsv2 or hybrid? What is mounted to
/sys/fs/cgroup and below?

Was the container configured to use either?

This is new payload on old host?

if you force container into cgroupsv1 mode as the host (by adding
systemd.unified_cgroup_hierarchy=no to the nspawn cmdline, does that
work?

Generally, systemd should discover everything on its own and just work
when run in an older container manager/cgroup environment. But it's
not something we would regularly test.
