Hallo Leute,

seit dem heutigen Reboot fährt mein LXC-Container "www" nicht mehr hoch. Hab keine Ahnung was sich in der Zwischenzeit geändert haben könnte. Aus dem Log werde ich auch nicht schlau.
Hat jemand eine Idee?

Code:

Dann antworte ich mal selbst. Durch Ausprobieren dahinter gekommen. Anscheinend erwartet LXC dass die Configdatei unbedingt unter /etc/lxc/$CONTAINER/config liegt. Auch wenn das Init-Script ein CONFIGFILE= unterstützt.
Ein
Code:
ln -s /pfad/zu/meiner/www.conf /etc/lxc/www/config
hat geholfen.

Ich habe ein ähnliches problem, aber mit ein unprivilegierten container.

Hast du oder jemand anders eine idee was da falsch läuft? Einen softlink wie bei deiner lösung wüsste ich jetzt nicht anzulegen.

die allgemeine konfigurationsdatei:
~/.config/lxc/default.conf
und die daraus generierte:
~/.local/share/lxc/playtime3/config


UPDATE: Das hat sich mit verwendung von cgmanager geändert, was noch übrig bleibt ist
Code:
lxc-start 1451059901.219 ERROR    lxc_cgmanager - call to cgmanager_move_pid_sync failed: invalid request
