Package: systemd
Version: 232-25+deb9u4
Description of problem:
After a 'systemctl daemon-reload' followed by any service 'systemctl
restart xxx' the blkio, cpu,cpuacct、memory cgroup path changed.
Steps to Reproduce:
1. Create and launch a basic VM
2. Check that the cgroups are mapped properly for example with 'virsh
memtune VM_NAME'
3. Execute 'systemctl daemon-reload'
4. Restart _any_ service on your machine, such as : systemctl restart libvirtd
before:
10:perf_event:/machine/qemu-1462-zyjtest.libvirt-qemu
9:blkio:/machine/qemu-1462-zyjtest.libvirt-qemu
8:cpu,cpuacct:/machine/qemu-1462-zyjtest.libvirt-qemu/emulator

# virsh memtune zyj_test
error: Unable to get memory parameters
error: Requested operation is not valid: cgroup memory controller is not mounted
I found a similar description at :
https://bugzilla.redhat.com/show_bug.cgi?id=1140215
And I had checked this systemd version had merged the patches.
core: introduce new Delegate=yes/no property controlling creation of
cgroup subhierarchies
core: don't migrate PIDs for units that may contain subcgroups, do
this only for leaf units
However, this issue is still exist.

Is the Delegate= option set for those cgroup hierarchies created by libvirt?
Since I can't reproduce the issue and no further information was
provided, I'm closing this issue.
