Hi all I have CentOS Linux release 7.0.1406, libvirt 1.2.7 installed. Just after create and start inside LXC container present cgroups. Example for memory: [root@ce7-t1 /]# ls -la /sys/fs/cgroup/memory/ total 0 drwxr-xr-x 2 root root 0 Sep 15 17:14 . drwxr-xr-x 12 root root 280 Sep 15 17:14 .. -rw-r--r-- 1 root root 0 Sep 15 17:14 cgroup.clone_children --w--w--w- 1 root root 0 Sep 15

Hello, I have a simple C program that uses libguestfs to extract info about disk usage from a libvirt domain. It works when ran manually as root, but fails when started as a systemd service. I'm attaching the service file, source code and verbose logs from both the successful manual run and from the service journal. SELinix is disabled. Error messages: libguestfs:

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
