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 ?
