I have a problem with it: Also it would be nice to know how lxc 1.1.0 can be made to run a container again. It cannot start any lxc container with the error that it cannot find a dev, .. etc. under /var/lib/lxc/rootfs as /var/lib/lxc/rootfs/dev/shm Needles to say with the previous version of lxc it did work. hand start: # lxc-start -n mlsrvr -f /etc/lxc/mlsrvr/config -F lxc: cgmanager.c: lxc_cgmanager_escape: 329 call to cgmanager_move_pid_abs_sync(name=systemd) failed: invalid request lxc-start: conf.c: mount_entry: 1705 No such file or directory - failed to mount 'shm' on '/var/lib/lxc/rootfs/dev/shm' lxc-start: conf.c: lxc_setup: 3815 failed to setup the mount entries for 'mlsrvr' lxc-start: start.c: do_start: 699 failed to setup the container lxc-start: sync.c: __sync_wait: 51 invalid sequence number 1. expected 2 lxc-start: start.c: __lxc_start: 1157 failed to spawn 'mlsrvr' lxc-start: lxc_start.c: main: 344 The container failed to start. lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options. Other containers also fail, but on different filesystems, but all on /var/lib/lxc/rootfs # lxc-start -n test -f /etc/lxc/test/config -F lxc: cgmanager.c: lxc_cgmanager_escape: 329 call to cgmanager_move_pid_abs_sync(name=systemd) failed: invalid request lxc-start: conf.c: lxc_mount_auto_mounts: 802 No such file or directory - error mounting /var/lib/lxc/rootfs/proc/sysrq-trigger on /var/lib/lxc/rootfs/proc/sysrq-trigger flags 4096 lxc-start: conf.c: lxc_setup: 3805 failed to setup the automatic mounts for 'test' lxc-start: start.c: do_start: 699 failed to setup the container lxc-start: sync.c: __sync_wait: 51 invalid sequence number 1. expected 2 lxc-start: start.c: __lxc_start: 1157 failed to spawn 'test' lxc-start: lxc_start.c: main: 344 The container failed to start. lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options. Reproducible: Always Steps to Reproduce: 1. upgrade system to current versions 2. restart running containers 3. Actual Results: see description, even after first installing lxc again + cgmanager and installing cgmanager as well. Expected Results: just a slight interruption of a container service instead of a break down.
emerge --info and emerge -pv lxc please
Lots of things have changed in 1.1.0. https://linuxcontainers.org/lxc/news/ So be prepared to perform some migration steps if you switch to 1.0.X I don't think there is anything wrong with our LXC just your config files need some tweaking.

I agree, but i don't have any idea of where to begin.
I would start by removing all the lxc.mount lines in the configuration files and introduce them one by one. But we can't support you via bugzilla unless you prove this is an LXC bug. You are better of using #gentoo on IRC or gentoo-user ML or the forums
there's more problems... lxc-can't create a new gentoo; A debian can be made, but doesn't start. # lxc-create -t gentoo -n test2 -P /rawstore/test2 --dir=/rawstore/test2/rootfs --config /rawstore/test2/config ### set_default_arch: default arch/variant autodetect... => Got: arch=amd64 variant=amd64 Attempting to obtain an exclusive lock (timeout: 60 sec) named "cache-amd64-amd64"... => done. => Executing "do_all" ###### cache_setup(): doing cache preparation ### cache_precheck(): doing some pre-start checks ... ### cache_stage3(): stage3 cache deployment...

After i rebooted the server, the cgmanager error is gone... (except that starting it it issues a pidfile not accessible error) # lxc-start -n mlsrv -f /etc/lxc/mlsrvr/config -F lxc-start: conf.c: mount_entry: 1705 No such file or directory - failed to mount 'shm' on '/var/lib/lxc/rootfs/dev/shm' lxc-start: conf.c: lxc_setup: 3815 failed to setup the mount entries for 'mlsrv' lxc-start: start.c: do_start: 699 failed to setup the container lxc-start: sync.c: __sync_wait: 51 invalid sequence number 1. expected 2 lxc-start: start.c: __lxc_start: 1157 failed to spawn 'mlsrv' lxc-start: lxc_start.c: main: 344 The container failed to start. lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.
after removing all mounts from the config it seems to work... lxc-start -n mlsrv -f /etc/lxc/mlsrvr/config -F INIT: version 2.88 booting OpenRC 0.12.4 is starting up Gentoo Linux (x86_64) [LXC] * /proc is already mounted * Mounting /run ...mount: permission denied * Unable to mount tmpfs on /run. * Can't continue. * Caching service dependencies ...

For the debian config the mounts in debian.common.conf && common.conf need to be removed.
Like I said there does not seem to be anything wrong with the LXC gentoo package. It just happens to need some effort from your end to migrate to the new version. Please use options i listed before to get support. Re-open this bug if you have proof this is an LXC gentoo bug.
Those files i mentioned: debian.common.conf && common.conf are both part of the standard package afaict., Thats, why i mentioned them. At least i didn't touch them before this issue. and updating them did help starting a freshly generated debian container. also it is impossible to create a gentoo container, it fails in a 404 error on a wget.

All these files are part of the upstream packages. They are not modified by the Gentoo ebuild. The gentoo lxc template is also part of the upstream package. If you are having problems with these files you need to open a bug upstream.
