Using virtCgroupNewSelf() is not correct with cgroups v2 because the the virt-host-validate process is executed from from the same cgroup context as the terminal and usually not all controllers are enabled by default. To do a proper check we need to use the root cgroup to see what controllers are actually available. Libvirt or systemd ensures that all controllers are available for VMs as well. This still doesn't solve the devices controller with cgroups v2 where there is no controller as it was replaced by eBPF. Currently libvirt tries to query eBPF programs which usually works only for root as regular users will get permission denied for that operation.

==============================
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.
Further information about the libvirt project can be found on the
website:
