Hi, My piece of code ( C langage) uses cgroups to retrieve counters related to cpu and memory usage related to KVM guests hosted by the host where this code runs. I noticed that depending on the O.S. running on the host , these counters are not found at the same location : CentOS 7 : ls /sys/fs/cgroup/cpuacct/machine.slice/machine-qemu\\x2drhel6.0.scope/vcpu0 cgroup.clone_children

Hi everyone, I am stuck in an (apparently) simple problem. In my event_controller I have the i_like_it action: def i_like_it @event = Event.find(params[:id]) ... # logic respond_to do |format| format.js end end In my case "i_like_it" is called with :method => PUT (it is an Ajax call, "i_like_it.js.erb" will be returned as a sc...

I have a RHEL6 that hosts many kvm virtual machines. It has been working fine for a couple years. I apply errata updates about once a week. In the last couple weeks, I've ran into a bug where the virtual machines start failing to start with a cgroup error message. If I reboot the host (very disruptive) then things start working normaly for a few days. Can I configure qemu/libvirt not to use

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was
