FWIW, my machine is also currently in that state: [root@jimmy ~]# pgrep systemd-nspawn 25917 [root@jimmy ~]# ps aux | grep [s]ystemd-nspawn root 25917 0.0 0.0 15380 200 ? Ss Jun26 0:00 /usr/bin/systemd-nspawn -b -M tl.dev -D /home/colin/Development/Work/container7 --bind=/home/colin/Development/Work/trunk [root@jimmy ~]# machinectl MACHINE CLASS SERVICE 0 machines listed. Not sure what caused it (machined logs say it was terminated just under 15mins after it started) I did have issues that a previous machine was not marked as having been stopped (i.e. machinectl listed it after I'd stop the service unit for the machine and systemd-nspawn processes had gone - pretty much the opposite problem!). I edited my unit file to rename the -M argument passed to systemd nspawn and reloaded systemd to reread the unit. I notice that machined said my old machine name terminated at the same time systemd was reloaded... What adds to the curiosity now I look at my logs, the current name was also ejected when I reloaded systemd again. Jun 26 13:58:44 jimmy systemd[1]: Reloading. Jun 26 13:58:44 jimmy systemd-machined[16851]: Machine tl.dev7 terminated. Jun 26 13:58:44 jimmy systemd[1]: Failed to enumerate devices: Invalid argument Jun 26 13:58:44 jimmy systemd[1]: Failed to reload: Invalid argument Jun 26 14:13:40 jimmy systemd[1]: Reloading. Jun 26 14:13:41 jimmy systemd-machined[16851]: Machine tl.dev terminated. Jun 26 14:13:41 jimmy systemd[1]: Failed to enumerate devices: Invalid argument Jun 26 14:13:41 jimmy systemd[1]: Failed to reload: Invalid argument Random guess: Perhaps machined is using fd storage facility of systemd and the reload borks it and it sees it as the machine going away?
