When libvirtd starts a VM it internally stores a path to the main cgroup. When we restart libvirtd we should get to the same state. When we start a VM on host with systemd the cgroup is created for us and the process is already placed into that cgroup and we detect the path created by systemd using /proc/$PID/cgroup. After that we create sub-cgroups and move all threads there. Once libvirtd is restarted we again detect the cgroup path using /proc/$PID/cgroup, but in this case we will get a different path because the main thread was moved to a "emulator" cgroup. Instead of ignoring the "emulator" directory when validating cgroups remove it completely when detecting cgroup otherwise cgroups will not work properly when libvirtd is restarted.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
