similar to: cgroups not working?

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

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

Hello All, From the last couple of days i have been spamming this mailing list with request for configuring Cgroup with libvirtd on Centos systems. I still can not find a permanent solution to limit host RAM to particular value,tried creating a separate hierarchy "mykvm" and changed in sysconfig/libvirtd after that vm's memory cgroup reflects this.But it is

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

Dear list, I am bulding a VM using libvirt and lxc for linux container. I have an issue with my cgroups settings: gabx@hortensia ➤➤ ~ # virsh start dahlia error: Failed to start domain dahlia error: internal error: No valid cgroup for machine dahlia My environement: Host : Arch Linux - systemd 208-11, libvirt 1.2.1-4 guest : Arch Linux , machine name : dahlia , /etc/libvirt/lxc/dahlia.xml ,

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

Hello, I'm running Debian Sid with libvirt/qemu/kvm packages from experimental: $ qemu --version QEMU emulator version 0.13.0 (Debian 0.13.0+dfsg-2), Copyright (c) 2003-2008 Fabrice Bellard $ kvm --version QEMU emulator version 0.13.0 (qemu-kvm-0.13.0 Debian 0.13.0+dfsg-2), Copyright (c) 2003-2008 Fabrice Bellard $ libvirtd --version libvirtd (libvirt) 0.8.6 /etc/libvirt/qemu.conf

On Centos 6.4 x64,with libvirt-0.10.2-18.el6.x86_64 i am trying to set "memory.limit_in_bytes" for all qemu process. changed "cgconfig.conf" group mygroup{ perm { admin { uid = root; gid = root; } task { uid = qemu; gid = kvm;

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 libvirt users, I'm using the cgroup with QEMU guests. At /etc/libvirt/qemu.conf, I have the following parameter: cgroup_controllers = [ "cpu" ] This controller is successfully mounted and libvirt is able to create subgroups for each VM, it's really great the cgroups support in libvirt. The problem is that I can only set the parameters of a given cgroup under the cpu

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

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
