aa-logprof complained about libvirt include file not found

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

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.
