Again with same Cgroup issue :)
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

libvirt/qemu and cgroups
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

cgroups not working?
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

Ok so here you've mounted all the cgroups controllers at the same

Hi Daniel,
Thanks a lot for your reply.
We have mounted all the cgoup controllers at "/dev/cgroup_<controller>" as
mentioned below.
ls /dev/ | grep cgroup
cgroup_cpu cgroup_cpuacct cgroup_cpuset cgroup_mem
On further debugging we dound that the "VCPU" directories are not being
created for our domains and hence the comamnd "cpu-stats

Can we disable write to /sys/fs/cgroup tree inside container ?

Each lxc container on node have mounted tmpfs for cgroups tree:

Cgroups : memory.limit_in_bytes and memory.usage_in_bytes includes file cache?
Hello All,
We were under the assumption that Cgroups memory controller, limits memory based on just the RSS size of the process.
However, i see that the process is getting killed even when the RSS size is very low compared to the limit in bytes.
For example:
cat memory.stat
cache 85880266752
rss 2441216
rss_huge 0
mapped_file 8192
swap 0

Permission issue with cgroups
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
