Meine CentOS LXC-Container werden auf einem Ubuntu 14.10-Computer nicht mehr gestartet. Ich denke, dass das Problem nach einem Neustart begann, bin mir aber nicht sicher.
Ich hatte ein ähnliches Problem nach einem yum-Update, als die Init-Skripte durch Standard-Skripte ersetzt wurden, die nicht LXC-fähig sind. Sie haben versucht, udev usw. zu starten. Aber dieses Mal habe ich dieses Problem für alle CentOS-Instanzen, auch für die neu erstellten.

BEARBEITEN : Es scheint, dass das Hinzufügen lxc.aa_allow_incomplete = 1in die Datei / var / lib / lxc / stash / config eine Problemumgehung für das Startproblem darstellt. Wie kann ich die App-Rüstung wieder mit CentOS LXC koexistieren lassen?
Von der Manpage lxc.container.conf:
lxc.aa_allow_incomplete
Apparmor profiles are pathname based. Therefore many file restrictions require mount restrictions to be effective against a determined attacker. However, these mount restrictions are not yet implemented in the
upstream kernel. Without the mount restrictions, the apparmor profiles still protect against accidental damager.
If this flag is 0 (default), then the container will not be started if the kernel lacks the apparmor mount features, so that a regression after a kernel upgrade will be detected. To start the container under partial
apparmor protection, set this flag to 1.
