Hi all I have CentOS Linux release 7.0.1406, libvirt 1.2.7 installed. Just after create and start inside LXC container present cgroups. Example for memory: [root@ce7-t1 /]# ls -la /sys/fs/cgroup/memory/ total 0 drwxr-xr-x 2 root root 0 Sep 15 17:14 . drwxr-xr-x 12 root root 280 Sep 15 17:14 .. -rw-r--r-- 1 root root 0 Sep 15 17:14 cgroup.clone_children --w--w--w- 1 root root 0 Sep 15

Hello All, We were under the assumption that Cgroups memory controller, limits memory based on just the RSS size of the process. However, i see that the process is getting killed even when the RSS size is very low compared to the limit in bytes. For example: cat memory.stat cache 85880266752 rss 2441216 rss_huge 0 mapped_file 8192 swap 0 pgpgin 29265847812 pgpgout 29244880354 pgfault

hi, I am currently investigating a bug with libvirt lxc. Whenever I do a systemctl daemon-reload on the host, my container loses his memory limit and then reports having access to 8 exabyte of memory. I have tracked the issue down to two parts: memory.limit_in_bytes jumps from the correct value to 9223372036854771712. libvirt lxc appears to set the memory limit in transient way without writing

It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive
