Hi, dbus on CentOS 7 lxc won’t work.

So I’m unable to start or query status units with systemd, for example:

systemctl status Failed to get D-Bus connection: No such file or directory

I have no issues with CentOS 8 container (debian 10 ones work fine too)
This is the output of ps aux on CentOS 7:

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.0 42712 3860 ? Ss 20:11 0:00
/lib/systemd/systemd systemd.unified_cgroup_hierarchy=1

On CentOS 8 instead:
