linux – CGroups内存限制不起作用

# lxc-cgroup -n maxdaniel981 memory.limit_in_bytes 134217728
lxc_container: Failed to assign '134217728' value to 'memory.limit_in_bytes' for 'maxdaniel981'

然后我查了/ proc / cgroups：

# cat /proc/cgroups
#subsys_name    hierarchy       num_cgroups     enabled
cpuset  2       3       1
cpu     3       3       1
cpuacct 3       3       1
memory  0       1       0
devices 4       3       1
freezer 5       3       1
net_cls 6       3       1
blkio   7       3       1
perf_event      8       3       1
net_prio        6       3       1

它看起来像cgroups_memory被禁用,但我在/ etc / default / grub中启用了内核标志并使用update-grub更新了grub

# cat /etc/default/grub
# If you change this file,run 'update-grub' afterWARDs to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file,see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DIStriBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="cggroup_enable=memory swapaccount=1"
GRUB_CMDLINE_LINUX="cggroup_enable=memory swapaccount=1"

CGroup安装在/ etc / fstab中就像这样;

cgroup        /sys/fs/cgroup  cgroup  defaults        0       0

有人可以帮我解决这个问题吗？我使用的是Debian jessie,我的内核版本是3.16.0-4-amd64.
