   5 Subject: [PATCH] vircgroup: Ensure /machine group is associated with its
   6  parent.
   7
   8 Call first virCgroupNew on the parent group virCgroupNewPartition if
   9 it is available on before the creation of the child group.  This
  10 ensures that the creation of a first level group on the unified
  11 architecture, as the check at virCgroupV2ParseControllersFile as the
  12 parent file is there.

  14 Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1760233
