Hi, I havent tried a 3.13 kernel yet but these informaitons are applicable to 3.10 kernels (and olders too). With the util-vserver supplied on the BenG repository you dont need to manually mount the cgroups, memory limit support should be loaded automatically. As for modifying limits on /etc/vservers/<guest>/cgroup/memory, the limits will only be used at the VServer start, not if the VServer is already running. You can change the live value on : /dev/cgroup/<guest>/memory.* (wont be kept at reboot). I am not sure that putting an "*G" argument will work, i personally use integer values such as : VSERVERNAME=thevservername MEMLIMITGB=4 [[ ! -d "/etc/vservers/${VSERVERNAME}/cgroup" ]] && mkdir /etc/vservers/${VSERVERNAME}/cgroup echo $((${MEMLIMITGB}*1024*1024*1024)) > /etc/vservers/${VSERVERNAME}/cgroup/memory.limit_in_bytes echo $((${MEMLIMITGB}*1024*1024*1024)) > /etc/vservers/${VSERVERNAME}/cgroup/memory.memsw.limit_in_bytes perl -i -pe 's/^#(virt_mem)/\1/' /etc/vservers/${VSERVERNAME}/cflags echo $((${MEMLIMITGB}*1024*1024*1024)) > /dev/cgroup/${VSERVERNAME}/memory.limit_in_bytes echo $((${MEMLIMITGB}*1024*1024*1024)) > /dev/cgroup/${VSERVERNAME}/memory.memsw.limit_in_bytes On 31/03/2014 16:37, Tomasz Pajor wrote: > Hi, > > I have problem with setting up memory limit on a vserver. > I'm using 3.13.6-vs2.3.6.11-beng from repo.psand.net. > > Steps > - added "cgroup_enable=memory swapaccount=1" to GRUB_CMDLINE_LINUX > - added "none /dev/cgroup cgroup cpu,cpuset,memory 0 0" to /etc/fstab > - added "INFO_INIT,VIRT_MEM,VIRT_UPTIME,VIRT_LOAD,REBOOT_KILL" to cflags > of the guest > - mkdir /etc/vservers/.defaults/cgroup > - mkdir /etc/vservers/<guest>/cgroup > - echo "4G" > /etc/vservers/<guest>/cgroup/memory.limit_in_bytes > - echo "8G" > /etc/vservers/<guest>/cgroup/memory.memsw.limit_in_bytes > > When I enter the guest, limits are not applied, also when I run > vserver-stat I got "open(memory.stat): No such file or directory". > > Can anyone point out what am I doing wrong?
