Probably not the best list, but I suppose others are trying to use their Fedora environments as a test bed for learning how to use control groups.... before going to production level OS and hw Attempts done on both F14 and F13 x86_64 but apparently without success.. Reporting the F14 ones, where cg commands were used. Fedora host is a machine with one quad-core AMD Athlon(tm) II X4 630 Processor - start a Qemu/KVM wxp guest configured with one cpu and started with pid 4944 - Started the cgconfig service with its default parameters so that I have: # cat /proc/mounts |grep cg cgroup /cgroup/cpuset cgroup rw,relatime,cpuset 0 0 cgroup /cgroup/cpu cgroup rw,relatime,cpu 0 0 cgroup /cgroup/cpuacct cgroup rw,relatime,cpuacct 0 0 cgroup /cgroup/memory cgroup rw,relatime,memory 0 0 cgroup /cgroup/devices cgroup rw,relatime,devices 0 0 cgroup /cgroup/freezer cgroup rw,relatime,freezer 0 0 cgroup /cgroup/net_cls cgroup rw,relatime,net_cls 0 0 cgroup /cgroup/ns cgroup rw,relatime,ns 0 0 - created a hierarchy with name wxp and controller cpuset # cgcreate -g cpuset:/wxp - configured the hierarchy to use only processors 2,3 (out of 0-4 available) # cgset -r cpuset.cpus=2-3 wxp - configured the hierarchy cpuset.mem parameter (otherwise I get "no space feft on device" error when I then attempt to put tasks in control group wxp... still to understand the exact meaning of this parameter) # cgset -r cpuset.mems=0 wxp - put my qemu/kvm pid inside the control group wxp # cgclassify -g cpuset:/wxp 4944 So that now I have: # cat /cgroup/cpuset/wxp/tasks 4944 - Run cpu freebenchmark 2 on guest The guest consumes one whole cpu during the bench, but still floating around all the four available host cpus during the 46 seconds duration. At least this is what "top" on host is telling me..... Is top buggy or cgroups not applied? I'm keeping on reading rh el 6 control groups manual but in the mean time if anyone can give advise, I thank him/her in advance.
