This is really strongly

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 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

Hi, I'm trying to use cgroups to limit the apache webserver but this doesn't seem to work as far as I can tell. I modified cgconfig.conf like this: group webserver { cpu { cpu.shares="250"; } } and addes this to cgrules.conf: *:httpd * webserver Looking into the "webserver" cgroup shows that the pid's of

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, First post, so please be nice ; ) I am trying to set my linux vlc as default media player for wine. I am trying to do that because i use a software called TVAnts to tune tv channels and I would like to skip one step of the process which is starting vlc or any other media player and point it to the address of the stream. something like: $ vlc http://localhost:16900/1.asf As I understand

Dear list, I am bulding a VM using libvirt and lxc for linux container.

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

I have a matrix of values... for exemple the matrix could be 100 rows and 50 columns... I would like to resample the matrix to obtain a new matrix -> a 10x5 matrix So i need to calculate a new value for every cell, i would like to use a weightened mean to do this. I explain this thing better: In the exemple the original matrix would be divided into 50 partial-matrix, for every partial-matrix

Tried with commenting out cgroup_controllers but with no change. Tried also unmounting /sys/fs/cgroup and mount the cgroups in a subfolder hierarchy manually but it remounted still all together (I think this is related at the unmounting support going away, I'm with kernel 3.10-rc4 on the test machine). So I had a look at Slackware's init system's scripts: /sys/fs/cgroup is mounted in

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 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
