I defined 512MB "soft" and 1GB "hard" limits: host # more /etc/vservers/vs6/cgroup/memory.limit_in_bytes 536870912 host # more /etc/vservers/vs6/cgroup/memory.memsw.limit_in_bytes 1073741824 host # more /dev/cgroup/vs6/memory.limit_in_bytes 536870912 host # more /dev/cgroup/vs6/memory.memsw.limit_in_bytes 1073741824 Yet in "vs6" guest I still see the whole 16GB RAM & 50GB swap: vs6 # free total used free shared buffers cached Mem: 16447700 426588 16021112 0 32840 38804 -/+ buffers/cache: 354944 16092756 Swap: 52428732 0 52428732 So where is the problem? What am I doing wrong? Jarry -- _______________________________________________________________ This mailbox accepts e-mails only from selected mailing-lists!
