Hi,
As told in "Control Groups Resource Management" libvirt page :
Legacy cgroups layout
Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was located. So if libvirtd was placed at /system/libvirtd.service by systemd, the groups for each virtual machine / container would be located at /system/libvirtd.service/libvirt/{qemu,lxc}/$VMNAME. In addition to this, the QEMU drivers further child groups for each vCPU thread and the emulator thread(s). This leads to a hierarchy that looked like
I just skimmed through the question, but wouldn't reading '/proc/$(pidof libvirtd)/cgroup' or cat /proc/$QEMU_PID/cgroup be enough?
I'm trying to retrieve this layout :
$ROOT

+- system

+- libvirtd.service

+- libvirt

+- qemu

| +- vm1

| | +- emulator
| | +- vcpu0

| | +- emulator
| | +- vcpu0
| | +- vcpu1

| +- vm3

| +- emulator
| +- vcpu0
| +- vcpu1
How may I find where systemd has placed libvirtd ?
I use libvirt 0.10.2 on a RHEL6 2.6.32-431.el6.x86_64
Thx for help.
