similar to: RHEL6 cgroup error after a few days of uptime

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, I'm running OpenStack to manage LXC instance through libvirt. The same setting runs perfectly well on Ubuntu 12.04, while on CentOS 6u3, libvirt dumped following message when starting lxc instance. virsh -c lxc:/// start instance-00000032 error: internal error The 'cpuacct', 'devices' & 'memory' cgroups controllers must be mounted Really appreciated if

Hello, I'm trying to use libvirt as a non-root user to obtain statistics on the CPU usage by VMs using the Python API. I'm performing basically the following steps: import libvirt conn = libvirt.openReadOnly(None) dom = conn.lookupByUUIDString('268e38ea-1bc7-41e4-c19e-8eff682e58e4') dom.getCPUStats(True, 0) However, they result in the following error: libvir: QEMU Driver

Hi there, Do you know if there is a way to modify how libvirt interacts with the cgroup? Because, I successfully add the /dev/net/tun support in my LXC container by doing: echo c 10:200 rwm >> /cgroup/libvirt/lxc/instance-00000005/devices.allow But when I restart the instance/LXC container, this option has gone. How can I make this persistant? Is there a configuration file? Thanks

Hi, We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1 on our linux machine. After this upgrade "virsh cpu-stats <domain>" command is not working on our HardWare. *virsh # cpu-stats test error: Failed to retrieve CPU statistics for domain 'test' error: internal error error accessing cgroup cpuacct for vcpu* ** *# cat /proc/cgroups #subsys_name

Is there a way to automatically set the permissions of cgroups directories created by libvirt when a VM is launched? Although it looks like I can set permissions on top-level /cgroup directories via cgconfig.conf, the cgconfig.conf manpage says "Permissions are related only to enclosing control group and are not inherited by subgroups.". From this, I believe that when libvirt

Hi all I have CentOS Linux release 7.0.1406, libvirt 1.2.7 installed. Just after create and start inside LXC container present cgroups. Example for memory: [root@ce7-t1 /]# ls -la /sys/fs/cgroup/memory/ total 0 drwxr-xr-x 2 root root 0 Sep 15 17:14 . drwxr-xr-x 12 root root 280 Sep 15 17:14 .. -rw-r--r-- 1 root root 0 Sep 15 17:14 cgroup.clone_children --w--w--w- 1 root root 0 Sep 15

Hi I was asking about the fedora 14 kernel if it is good enough for cgroup usage because I am trying to set a cgroup under cpu subsytem ( /dev/cgroup/cpu/group1/ ) that have /cpu.rt_runtime_us of 100000 while cpu.rt_period_us has a value of 1000000 i.e a ratio of 1/10 . still when I run a task (endless loop) in that group (cgexec -g cpu,cpuset:group1 ./test) it gets all the cpu core time

Hello All, i am trying to set "memory.limit_in_bytes" for all process created by libvirt.But i am not able to achieve this on RHEL systems in Ubuntu servers creating memory cgroup for "libvirt-qemu" user solves the issue.But in case of RHEL system i tried to create a group by editing "cgconfig.conf" and then changing cgrules.conf and restarted cgconfig and

This is really strongly

Dear list, I am building a Arch server on my Arch box. My tools are QEMU/KVM and libvirt to manage the guest, systemd as system manager. I am looking at implementing the Linux Control Groups facilities for resource management. Even after long hours of reading, I am not quite sure about how to deal with the cgroups facilities. First, do I really need to care about all that, or libvirt and

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
