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 cgroup.procs cpuacct.usage cpu.cfs_period_us cpu.rt_period_us cpu.shares notify_on_release cgroup.event_control cpuacct.stat cpuacct.usage_percpu cpu.cfs_quota_us cpu.rt_runtime_us cpu.stat tasks ]# RHEL6 : ls /cgroup/cpuacct/libvirt/qemu/VM_Orion-1/vcpu0 cgroup.event_control cgroup.procs cpuacct.stat cpuacct.usage cpuacct.usage_percpu notify_on_release tasks 1) May I assume that their meanings is identical ? 2) Is this difference due to the O.S. or to libvirt ? 3) I presume I've to check this point on Ubuntu , Debian and Fedora .
