hi, I am currently investigating a bug with libvirt lxc. Whenever I do a systemctl daemon-reload on the host, my container loses his memory limit and then reports having access to 8 exabyte of memory. I have tracked the issue down to two parts: memory.limit_in_bytes jumps from the correct value to 9223372036854771712. libvirt lxc appears to set the memory limit in transient way without writing a config for systemd. I can't prevent memory.limit_in_bytes changing by setting the correct value through systemctl set-property --runtime <scope> MemoryLim...

I'm trying to permanently change memory allocation for a libvirt-lxc domain. So far I tried changing memory in memory.limit_in_bytes under /cgroup/memory/libvirt/lxc/<container>/.  This didn't help. It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive LXC domain reboot. Any help would...

...there should be no need for anyone > to minimize this. Once or twice, one of our VMs was OOM killed because it reached 1.5 * memory limit for its cgroup. Here is an 8GB, instance. Libvirt created cgroup with 12.3GB memory limit, which we have filled to 98% [root@dev-cmp08 ~]# cgget -r memory.limit_in_bytes -r memory.usage_in_bytes libvirt/qemu/i-000009fa libvirt/qemu/i-000009fa: memory.limit_in_bytes: 13215727616 memory.usage_in_bytes: 12998287360 The 4G difference is the cache. That's why I'm so interested in what is consuming the cache on a VM which should be caching in guest only. Rega...

Has anyone seen this issue? We're running containers under CentOS 7.2 and some of these containers are reporting incorrect memory allocation in /proc/meminfo. The output below comes from a system with 32G of memory and 84GB of swap. The values reported are completely wrong. # cat /proc/meminfo MemTotal: 9007199254740991 kB MemFree: 9007199224543267 kB MemAvailable: 12985680

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 cgrule...

...up 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 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...
