[libvirt-users] C group hierarchy and libvirtd
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;
}
}
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" is getting
applied only to libvirtd process.VM are not following
memory.limit_in_bytes set to "mygroup".
1. how can i set this globally so that all virtual machines follow
that, i dont want to create a new group for that if libvirt supports
it.
2.Is there any way i can avoid extra hierarchy and create virtual
machines memory cgroup under "/cgroup/memory/kvm/" instead of
"/cgroup/memory/mygroup/libvirt/qemu/" ?
please help me fix this issue.I have this working on ubuntu servers
where i specified "libvirt-qemu" user and VMs follow that cgroup for
memory.
