Hi, With a non-root user account, I am launching virtual machines and would like to get CPU stats for each Core (using python API or not) but face the following problem: - When I issue the command "virsh --readonly cpu-stats MY_DOMAIN" I got the following error: error: Failed to retrieve CPU statistics for domain 'MY_DOMAIN' error: Requested operation is not valid: cgroup CPUACCT controller is not mounted - I checked that cgroup is well mounted: $ cat /proc/mounts | grep cgroup tmpfs /sys/fs/cgroup tmpfs ro,nosuid,nodev,noexec,mode=755 0 0 cgroup /sys/fs/cgroup/systemd cgroup rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/usr/lib/systemd/systemd-cgroups-agent,name=systemd 0 0 cgroup /sys/fs/cgroup/devices cgroup rw,nosuid,nodev,noexec,relatime,devices 0 0 cgroup /sys/fs/cgroup/hugetlb cgroup rw,nosuid,nodev,noexec,relatime,hugetlb 0 0 cgroup /sys/fs/cgroup/pids cgroup rw,nosuid,nodev,noexec,relatime,pids 0 0 cgroup /sys/fs/cgroup/freezer cgroup rw,nosuid,nodev,noexec,relatime,freezer 0 0 cgroup /sys/fs/cgroup/cpuset cgroup rw,nosuid,nodev,noexec,relatime,cpuset 0 0 cgroup /sys/fs/cgroup/cpu,cpuacct cgroup rw,nosuid,nodev,noexec,relatime,cpuacct,cpu 0 0 cgroup /sys/fs/cgroup/net_cls,net_prio cgroup rw,nosuid,nodev,noexec,relatime,net_prio,net_cls 0 0 cgroup /sys/fs/cgroup/perf_event cgroup rw,nosuid,nodev,noexec,relatime,perf_event 0 0 cgroup /sys/fs/cgroup/blkio cgroup rw,nosuid,nodev,noexec,relatime,blkio 0 0 cgroup /sys/fs/cgroup/memory cgroup rw,nosuid,nodev,noexec,relatime,memory 0 0 $ cat /proc/cgroups #subsys_name hierarchy num_cgroups enabled cpuset 6 1 1 cpu 7 1 1 cpuacct 7 1 1 memory 11 1 1 devices 2 1 1 freezer 5 1 1 net_cls 8 1 1 blkio 10 1 1 perf_event 9 1 1 hugetlb 3 1 1 pids 4 1 1 net_prio 8 1 1 - I checked the system-cgtop but don't have no CPU info for my VMs (first line starting with /): Path Tasks %CPU Memory Input/s Output/s / 332 808.0 21.3G - - /system.slice/auditd.service 1 - - - - /system.slice/crond.service 1 - - - - /system.slice/dbus.service 1 - - - - /system.slice/gssproxy.service 1 - - - - /system.slice/irqbalance.service 1 - - - - /system.slice/ksmtuned.service 2 - - - - /system.slice/libvirtd.service 1 - - - - /system.slice/lvm2-lvmetad.service 1 - - - - /system.slice/polkit.service 1 - - - - /system.slice/rhnsd.service 1 - - - - /system.slice/rhsmcertd.service 1 - - - - /system.slice/rsyslog.service 1 - - - - /system.slice/sshd.service 1 - - - - /system.slice/system-getty.slice/getty@tty1.service 1 - - - - /system.slice/systemd-journald.service 1 - - - - /system.slice/systemd-logind.service 1 - - - - /system.slice/systemd-udevd.service 1 - - - - /system.slice/tuned.service 1 - - - - /user.slice/user-3972.slice/session-15191.scope 3 - - - - /user.slice/user-3972.slice/session-16005.scope 4 - - - - /user.slice/user-3972.slice/session-16019.scope 10 - - - - Thanks by advance for your help!
