[libvirt] [PATCH 2/2] vircgroup: Ensure /machine group is associated with its parent
Call first virCgroupNew on the parent group virCgroupNewPartition if
it is available on before the creation of the child group. This
ensures that the creation of a first level group on the unified
architecture, as the check at virCgroupV2ParseControllersFile as the
parent file is there.
