Difficulty configuring Cgroups on redhat/centos
...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 libvirtd but still virtual machines are not
following what is mentioned in config,instead they follow cgroup
libvirt/qemu/virtualmachine-name ,is there any way i can set global
cgroup values for all process rather editing each process
configuration or how can i confi...

libvirt/qemu and cgroups
...agement. 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 systemd
will manage the resource in an efficient way right out of the box?
If not, It's all about /etc/cgconfig.conf and cgrules.conf. I am
honestly not sure :
-what are the correct mount points for cpu, memory etc in the
/sys/fs/cgroup directory .
- which directories am I supposed to mk, if any ?
Then, Archwiki[1] says:
# cgcreate -a $USER -g memory,cpu:groupname
- what is the groupename I shall create (qemu*, MyMachin...

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 the httpd
processes are correctly assigned:
$ cat /cgroup/cpu/webserver/tasks
6191
6193
6194
6195
6196
6197
6207
Yet when I run a php file with a dummy loop I get a process w...

C group hierarchy and libvirtd
...;
}
task {
uid = qemu;
gid = kvm;
}
}
memory {
memory.limit_in_bytes = 61G;
}
}
and also added "CGROUP_DAEMON=memory:/mygroup" in sysconfig/libvirtd
and in cgrules.conf and then restarted services.
Now i can see created virtual machines use cgroup hierarchy
"/cgroup/memory/mygroup/libvirt/qemu/virtualmachine1/" instead of
"/cgroup/memory/libvirt/qemu/virtualmachine1/".
The issue is "memory.limit_in_bytes" set to "mygroup&q...

Again with same Cgroup issue :)
...rmanent 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 not obeying "memory.limit_in_bytes" set in
"mykvm" group,i als specified it in cgrules.conf and restarted it.If i
change that in "/cgconfig/memory/mykvm/libvirt/qemu/memory.limit_in_bytes
" its working.But that is dynamic as i am not able to find a way to
mention that in "cgconfig.conf".
How can i make sub hierarchies follow what is set in parent cgroup?
eg: if c...
