Title:
  aa-logprof complained about libvirt include file not found on K-s390x

Status in ubuntu-kernel-tests:
  New

Bug description:
  When you try to run aa-logprof on s390x instances (zVM / LPAR), it will complain about:
  $ aa-logprof

  ERROR: Include file /etc/apparmor.d/libvirt/libvirt-df90c3d2-e35c-4914-9b8a-a6958234d0e0.files not found
  $ echo $?
  1

  This is causing test failures in ubuntu_qrt_apparmor tests, for those tests that will call aa-logprof, because of this non-zero return value:
  * ApparmorTest.test_lp652674
  * ApparmorTest.test_lp1243932_send
  * ApparmorTest.test_lp1243932_receive
  * ApparmorTest.test_lp1243932_bind
  * ApparmorTestsuites.test_utils_testsuite
  * ApparmorTestsuites.test_utils_testsuite3

  One example output:
   Running 'python3 ./test-apparmor.py -v ApparmorTest.test_lp652674'
   Running test: './test-apparmor.py' distro: 'Ubuntu 22.10' kernel: '5.19.0-28.29 (Ubuntu 5.19.0-28.29-generic 5.19.17)' arch: 's390x' uid: 0/0 SUDO_USER: 'ubuntu')

  This is not a regression, it's just the ubuntu_qrt_apparmor test
  granularity improvement (bug 1982439) make it easier to spot this
  failure.

  Take a closer look into /usr/lib/python3/dist-packages/apparmor/aa.py,
  this failure happens in loadincludes(), when trying to load the file
  in /etc/apparmor.d/libvirt/

  $ ls
  libvirt-6e3ec251-b475-43eb-bbc1-a7844b0d8e86 TEMPLATE.lxc  TEMPLATE.qemu
  $ cat libvirt-6e3ec251-b475-43eb-bbc1-a7844b0d8e86
  #
  # This profile is for the domain whose UUID matches this file.
  #

  #include <tunables/global>

  profile libvirt-6e3ec251-b475-43eb-bbc1-a7844b0d8e86 flags=(attach_disconnected) {
    #include <abstractions/libvirt-qemu>
    #include <libvirt/libvirt-6e3ec251-b475-43eb-bbc1-a7844b0d8e86.files>

  }
  $

  The include file here, libvirt-6e3ec251-b475-43eb-
  bbc1-a7844b0d8e86.files, will cause this file not found error.

  It seems this /etc/apparmor.d/libvirt/libvirt-* file was created with
  uvt-kvm. One new file will be created when we run the
  ubuntu_kvm_smoke_test once.
