[lxc-users] lxc_cgmanager - call to cgmanager_set_value_sync failed

[Flo]

Hi,

I just installed a fresh Ubuntu 14.04 amd64 and tried to start a container
with the following configuration:

# Common configuration
# Autostart the container after a host reboot
lxc.start.auto = 1

# Default pivot location
lxc.pivotdir = lxc_putold

# Default mount entries
lxc.mount.entry = proc proc proc nodev,noexec,nosuid 0 0
lxc.mount.entry = sysfs sys sysfs defaults 0 0
lxc.mount.entry = /sys/fs/fuse/connections sys/fs/fuse/connections none
bind,optional 0 0
lxc.mount.entry = /sys/kernel/debug sys/kernel/debug none bind,optional 0 0
lxc.mount.entry = /sys/kernel/security sys/kernel/security none
bind,optional 0 0
lxc.mount.entry = /sys/fs/pstore sys/fs/pstore none bind,optional 0 0

# Default console settings
lxc.devttydir = lxc
lxc.tty = 4
lxc.pts = 1024

# Default capabilities
lxc.cap.drop = sys_module mac_admin mac_override sys_time

# When using LXC with apparmor, the container will be confined by default.
# If you wish for it to instead run unconfined, copy the following line
# (uncommented) to the container's configuration file.
#lxc.aa_profile = unconfined

# To support container nesting on an Ubuntu host while retaining most of
# apparmor's added security, use the following two lines instead.
#lxc.aa_profile = lxc-container-default-with-nesting
#lxc.hook.mount = /usr/share/lxc/hooks/mountcgroups

# Uncomment the following line to autodetect squid-deb-proxy configuration
on the
# host and forward it to the guest at start time.
#lxc.hook.pre-start = /usr/share/lxc/hooks/squid-deb-proxy-client

# If you wish to allow mounting block filesystems, then use the following
# line instead, and make sure to grant access to the block device and/or
loop
# devices below in lxc.cgroup.devices.allow.
#lxc.aa_profile = lxc-container-default-with-mounting

# Default cgroup limits
lxc.cgroup.devices.deny = a
## Allow any mknod (but not using the node)
lxc.cgroup.devices.allow = c *:* m
lxc.cgroup.devices.allow = b *:* m
## /dev/null and zero
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
## consoles

## /dev/pts/*
lxc.cgroup.devices.allow = c 5:2 rwm
lxc.cgroup.devices.allow = c 136:* rwm
## rtc
lxc.cgroup.devices.allow = c 254:0 rm
## fuse
lxc.cgroup.devices.allow = c 10:229 rwm
## tun
lxc.cgroup.devices.allow = c 10:200 rwm
## full
lxc.cgroup.devices.allow = c 1:7 rwm
## hpet
lxc.cgroup.devices.allow = c 10:228 rwm
## kvm
lxc.cgroup.devices.allow = c 10:232 rwm
## To use loop devices, copy the following line to the container's
## configuration file (uncommented).
#lxc.cgroup.devices.allow = b 7:* rwm

# Container specific configuration
lxc.rootfs = /dev/lxc1/app01-jobs2-prodm
lxc.mount = /var/lib/lxc/app01-xxx/fstab
lxc.utsname = app01-xxx
lxc.arch = amd64

# Network configuration
lxc.network.type = veth
lxc.network.link = prodf
lxc.network.flags = up
lxc.network.name = front
lxc.network.hwaddr = 00:16:3f:6c:3b:28
lxc.network.type = veth
lxc.network.link = prodb
lxc.network.flags = up
lxc.network.name = back
lxc.network.hwaddr = 00:16:3b:c3:8c:a5

#
#
# write console output to file
lxc.console = /var/lib/lxc/app01-xxx/console.out
#
# restrict CPU time (default=1024)
#lxc.cgroup.cpu.shares = 1024
# restrict IO weight (range 10-1000)
#lxc.cgroup.blkio.weight = 1000
# limit memory
lxc.cgroup.memory.limit_in_bytes = 16G
##lxc.cgroup.memory.soft_limit_in_bytes = 15G
# memory + swap limit (20G - 16G = 4G SWAP)
lxc.cgroup.memory.memsw.limit_in_bytes = 20G

# enable cgroupd inside the container
lxc.mount.auto = cgroup:mixed

but starting the container failrs with:

      lxc-start 1398334434.479 ERROR    lxc_cgmanager - call to
cgmanager_set_value_sync failed: invalid request
      lxc-start 1398334434.479 ERROR    lxc_cgmanager - Error setting
cgroup memory.memsw.limit_in_bytes limit lxc/app01-jobs2-prodm
      lxc-start 1398334434.479 ERROR    lxc_cgmanager - Error setting
memory.memsw.limit_in_bytes to 20G for app01-xxx
      lxc-start 1398334434.479 ERROR    lxc_start - failed to setup the
cgroup limits for 'app01-xxx'
      lxc-start 1398334434.603 ERROR    lxc_start - failed to spawn
'app01-xxx'
      lxc-start 1398334434.603 ERROR    lxc_commands - command get_cgroup
failed to receive response

Is that hack:

cat << EOFlxc > /etc/init/lxc-unpriv-cgroup.conf
#start on starting systemd-logind and started cgroup-lite
#
#script
#    set +e
#
#    echo 1 > /sys/fs/cgroup/memory/memory.use_hierarchy
#
#    for entry in /sys/fs/cgroup/*/cgroup.clone_children; do
#        echo 1 > $entry
##    done
#
#    exit 0
#end script

still needed?
