Re: [lxc-users] lxc memory limit doesn't work

in fact. Today i setup lxd and lxc seperately. on lxd setup i used: lxc config set my-container limits.memory 4G and it worked. But i considered lxd is not quite stable for production. Than i used lxc then i created a container and edit conf-file lxc.cgroup.memory.limit_in_bytes = 2048M but

Re: [lxc-users] lxc memory limit doesn't work

I noticed that i have no /sys/fs/cgroup/lxc/ directory. Is it a problem? Instead: cgmanager and systemd directories exist. 2015-04-29 12:09 GMT+03:00 Fırat KÜÇÜK : > in fact. > > Today i setup lxd and lxc seperately. > > on lxd setup i used: > > lxc config set my-container limits.memory 4G > >

Re: [lxc-users] lxc memory limit doesn't work

Ah, OK. In that case, on the container, try: mount | grep lxcfs cat /proc/cpuinfo cat /proc/meminfo IF you have lxcfs correctly installed and used by the containers (as shown by mount command), cpuinfo and meminfo should contain container-specific values as set on cgroups (e.g. lxc.cgroup.cpuset.

Re: [lxc-users] lxc memory limit doesn't work

How did you install lxcfs? Looks like your version of cgmanger is not new enough. The ppa should also have updated cgmanager ... or if you have updated, you might simply need to reboot first. On Wed, Apr 29, 2015 at 5:29 PM, Fırat KÜÇÜK wrote: > call to move_pid_abs (all:/) failed: invalid requ
