Thanks, but a strange thing is that lxc performs different from docker. Can you try the following?
# sudo -i # lxc-start -n ubuntu1 # echo 1g > /sys/fs/cgroup/memory/lxc/ubuntu1/memory.limit_in_bytes # echo 1g > /sys/fs/cgroup/memory/lxc/ubuntu1/memory.memsw.limit_in_bytes # lxc-freeze -n ubuntu1 # echo 0 > /sys/fs/cgroup/memory/lxc/ubuntu1/memory.limit_in_bytes # cat /sys/fs/cgroup/memory/lxc/ubuntu1/memory.usage_in_bytes 0 Then, why the last command returns "0" ? Where is kmem? It makes me think that kmem has been drop. Do you know why the whole memory data including kmem is moved to swap, or a bug? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1568592 Title: bug of "memory.kmem.limit_in_bytes" and "memory.kmem.usage_in_bytes" Status in linux package in Ubuntu: Incomplete Bug description: In ubuntuxenial with linux kernel 4.4, "memory.kmem.limit_in_bytes" cannot be written, and the value of "memory.kmem.usage_in_bytes" is always 0.
