lxc-start autopkgtest-sid 20200421123647.929 NOTICE start - start.c:start:2041 - Exec'ing "/sbin/init" lxc-start autopkgtest-sid 20200421123647.929 NOTICE start - start.c:post_start:2052 - Started "/sbin/init" with pid "2749" lxc-start autopkgtest-sid 20200421123647.929 NOTICE start - start.c:signal_handler:393 - Received 17 from pid 2747 instead of container init 2749 lxc-start autopkgtest-sid 20200421123647.936 DEBUG start - start.c:signal_handler:411 - Container init process 2749 exited lxc-start autopkgtest-sid 20200421123647.936 INFO error - error.c:lxc_error_set_and_log:28 - Child <2749> ended on error (255) This seems to indicate that /sbin/init exited immediately after the container was started. I do not see such messages when I ran the same command. Could you run lxc-start -F -n autopkgtest-sid with -F? It may show error messages from /sbin/init in the container. My guess is that /var/lib/lxc/autopkgtest-sid/config needs lxc.init.cmd = /sbin/init systemd.unified_cgroup_hierarchy=1 (or alternatively lxc.mount.auto = cgroup:rw:force). In my Debian, lxc.init.cmd in /var/lib/lxc/autopkgtest-unstable-amd64/config was copied from /etc/lxc/default.conf when I ran "debci setup", which ran "lxc-create -t debian" as its child process, which copies /etc/lxc/default.conf into the container config. IMHO it seems a design flaw in LXC which needs different container config depending on the host cgroup hierarchy... Best regards, Ryutaroh
