Pavel Hrdina 6960a895ab vircgroupv2: properly free BPF prog and map FDs
When nested cgroup was introduced it did not properly free file
descriptors for BPF prog and map. With nested cgroups we create the BPF
bits in the nested cgroup instead of the VM root cgroup.

This would leak the FDs which would be the last reference to the prog
and map so kernel would not remove the resources as well. It would only
happen once libvirtd process exits.

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.
