--- Begin Message ---Package: lxc Version: 1:1.0.6-6 Severity: normal This isn't really a bug report but rather just to ask you some questions. For CPU related stuff, the man page quotes CONTROL GROUP This configuration will setup several control groups for the application, cpuset.cpus restricts usage of the defined cpu, cpus.share prioritize the control group, devices.allow makes usable the specified devices. lxc.cgroup.cpuset.cpus = 0,1 lxc.cgroup.cpu.shares = 1234 lxc.cgroup.devices.deny = a lxc.cgroup.devices.allow = c 1:3 rw lxc.cgroup.devices.allow = b 8:0 rw I set the same in the config file, and now I hope to contain the CPU to only a subset of the available logical CPUs. Inside the container, the output of getconf results in: ubuntu@trusty-test:~$ getconf _NPROCESSORS_ONLN 8 Whereas in reality, only 2 procs should be available. Do we see the need to build more intelligence inside the containers ? -- System Information: Debian Release: 8.0 APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (101, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages lxc depends on: ii init-system-helpers 1.22 ii libapparmor1 2.9.0-3 ii libc6 2.19-13 ii libcap2 1:2.24-6 ii libseccomp2 2.1.1-1 ii libselinux1 2.3-2 ii multiarch-support 2.19-13 ii python3 3.4.2-2 Versions of packages lxc recommends: ii debootstrap 1.0.66 ii openssl 1.0.1k-1 ii rsync 3.1.1-2+b1 Versions of packages lxc suggests: pn lua5.2 <none> -- Configuration Files: /etc/init.d/lxc changed: sysconfdir="/etc" bindir="/usr/bin" localstatedir="/var" mount_cgroups="yes" cgroups="cpuset cpu cpuacct devices freezer net_cls blkio perf_event" ! grep -qs cgroup_enable=memory /proc/cmdline || cgroups="$cgroups memory" BOOTGROUPS="onboot," SHUTDOWNDELAY=5 OPTIONS= STOPOPTS="-a -s" test ! -r /lib/lsb/init-functions || . /lib/lsb/init-functions test ! -r "$sysconfdir"/sysconfig/lxc || .
