[libvirt-users] Difficulty configuring Cgroups on redhat/centos
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 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 configure libvirt to use new configuration
file and use that group instead of default libvirt/qemu/ cgroup.
/etc/cgconfig.conf
mount {
cpuset = /cgroup/cpuset;
cpu = /cgroup/cpu;
cpuacct = /cgroup/cpuacct;
memory = /cgroup/memory;
devices = /cgroup/devices;
freezer = /cgroup/freezer;
net_cls = /cgroup/net_cls;
blkio = /cgroup/blkio;
}
group kvm {
perm {
admin {
uid = root;
gid = root;
}
task {
uid = qemu;
gid = kvm;
}
}
memory {
memory.limit_in_bytes = 61G;
}
}
and this on cgrules.conf
qemu memory kvm
Thanks for your help
