Package: lxc Version: 1:2.0.7-2 Severity: normal Dear Maintainer,
When trying to start a container, I get these errors: # lxc-start -n test -F lxc-start: cgroups/cgfs.c: lxc_cgroupfs_create: 901 Could not find writable mount point for cgroup hierarchy 11 while trying to create cgroup. lxc-start: cgroups/cgfs.c: cgroup_rmdir: 209 Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/systemd//user.slice/user-0.slice/session-1.scope lxc-start: cgroups/cgfs.c: cgroup_rmdir: 209 Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/systemd//user.slice/user-0.slice lxc-start: cgroups/cgfs.c: cgroup_rmdir: 209 Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/systemd//user.slice lxc-start: cgroups/cgfs.c: cgroup_rmdir: 209 Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/systemd/ lxc-start: start.c: lxc_spawn: 1108 Failed creating cgroups. lxc-start: start.c: __lxc_start: 1346 Failed to spawn container "test". lxc-start: tools/lxc_start.c: main: 366 The container failed to start. lxc-start: tools/lxc_start.c: main: 370 Additional information can be obtained by setting the --logfile and --logpriority options. If I enable systemd, lxc starts working. But then I have issues with other software, so I don't want to do that. Attached are my mounts, since I have the feeling this is related. Do I need some special systemd related cgroups for lxc, now? A few pointers in the documentation would be nice. :) -- System Information: Debian Release: 9.1 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-3-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages lxc depends on: ii init-system-helpers 1.48 ii libapparmor1 2.11.0-3 ii libc6 2.24-11+deb9u1 ii libcap2 1:2.25-1 ii libgnutls30 3.5.8-5+deb9u2 ii liblxc1 1:2.0.7-2 ii libseccomp2 2.3.1-2.1 ii libselinux1 2.6-3+b1 ii lsb-base 9.20161125 ii python3 3.5.3-1 ii python3-lxc 1:2.0.7-2 Versions of packages lxc recommends: ii bridge-utils 1.5-13 ii debootstrap 1.0.89 ii dirmngr 2.1.18-6 ii dnsmasq-base 2.76-5+b1 ii gnupg 2.1.18-6 ii iptables 1.6.0+snapshot20161117-6 ii libpam-cgfs 2.0.7-1 ii lxcfs 2.0.7-1 ii openssl 1.1.0f-3 ii rsync 3.1.2-1 ii uidmap 1:4.4-4.1 Versions of packages lxc suggests: pn apparmor <none> pn btrfs-tools <none> ii lvm2 2.02.168-2 -- no debconf information
