Bug Description
When creating a new VM definition using "virsh define" no apparmor profile was created and consequently the VM cannot be started
Furthermore, a manually created apparmor definition could not be loaded (according to error message)

libvirt.conf was modified as follows (see tags # ============= RE Change ============== # )
=======
# Master configuration file for the QEMU driver.
# All settings described here are optional - if omitted, sensible
# defaults are used.
# VNC is configured to listen on 127.0.0.1 by default.
# To make it listen on all public interfaces, uncomment
# this next option.
#
# NB, strong recommendation to enable TLS + x509 certificate
# verification when allowing public access
#
#vnc_listen = "0.0.0.0"
# Enable this option to have VNC served over an automatically created
# unix socket. This prevents unprivileged access from users on the
# host machine, though most VNC clients do not support it.
#
# This will only be enabled for VNC configurations that do not have
# a hardcoded 'listen' or 'socket' value. This setting takes preference
# over vnc_listen.
#
#vnc_auto_
# Enable use of TLS encryption on the VNC server. This requires
# a VNC client which supports the VeNCrypt protocol extension.
# Examples include vinagre, virt-viewer, virt-manager and vencrypt
# itself. UltraVNC, RealVNC, TightVNC do not support this
#
# It is necessary to setup CA and issue a server certificate
# before enabling this.
#
#vnc_tls = 1
# Use of TLS requires that x509 certificates be issued. The
# default it to keep them in /etc/pki/
# must contain
#
# ca-cert.pem - the CA master certificate
# server-cert.pem - the server certificate signed with ca-cert.pem
# server-key.pem - the server private key
#
# This option allows the certificate directory to be changed
#
#vnc_tls_
# The default TLS configuration only uses certificates for the server
# allowing the client to verify the server's identity and establish
# an encrypted channel.
#
# It is possible to use x509 certificates for authentication too, by
# issuing a x509 certificate to every client who needs to connect.
#
# Enabling this option will reject any client who does not have a
# certificate signed by the CA in /etc/pki/
#
#vnc_tls_
# The default VNC password. Only 8 bytes are significant for
# VNC passwords. This parameter is only used if the per-domain
# XML config does not already provide a password. To allow
# access without passwords, leave this commented out. An empty
# string will still enable passwords, but be rejected by QEMU,
# effectively preventing any use of VNC. Obviously change this
# example here before you set this.
#
#vnc_password = "XYZ12345"
# Enable use of SASL encryption on the VNC server. This requires
# a VNC client which supports the SASL protocol extension.
# Examples include vinagre, virt-viewer and virt-manager
# itself. UltraVNC, RealVNC, TightVNC do not support this
#
# It is necessary to configure /etc/sasl2/
# the desired SASL plugin (eg, GSSPI for Kerberos)
#
#vnc_sasl = 1
# The default SASL configuration file is located in /etc/sasl2/
# When running libvirtd unprivileged, it may be desirable to
# override the configs in this location. Set this parameter to
# point to the directory, and create a qemu.conf in that location
#
#vnc_sasl_dir = "/some/
# QEMU implements an extension for providing audio over a VNC connection,
# though if your VNC client does not support it, your only chance for getting
# sound output is through regular audio backends. By default, libvirt will
# disable all QEMU sound backends if using VNC, since they can cause
# permissions issues. Enabling this option will make libvirtd honor the
# QEMU_AUDIO_DRV environment variable when using VNC.
#
#vnc_allow_
# SPICE is configured to listen on 127.0.0.1 by default.
# To make it listen on all public interfaces, uncomment

# By default, if no graphical front end is configured, libvirt will disable
# QEMU audio output since directly talking to alsa/pulseaudio may not work
# with various security settings. If you know what you're doing, enable

# Override the port for creating both VNC and SPICE sessions (min).
# This defaults to 5900 and increases for consecutive sessions

#
# Minimum must be greater than or equal to 5900 as lower number would

# The default security driver is SELinux. If SELinux is disabled

# leaving SELinux enabled for the host in general, then set this
# to 'none' instead. It's also possible to use more than one security
# driver at the same time, for this use a list of names separated by
# comma and delimited by square brackets. For example:
#
# security_driver = [ "selinux", "apparmor" ]
#
# Notes: The DAC security driver is always enabled; as a result, the

# The default format for Qemu/KVM guest save images is raw; that is, the

# Keepalive protocol:
# This allows qemu driver to detect broken connections to remote

# to check if the daemon is still responding; keepalive_count is a
# maximum number of keepalive messages that are allowed to be sent
# to the daemon without getting any response before the connection
# is considered broken. In other words, the connection is
# automatically closed approximately after
# keepalive_interval * (keepalive_count + 1) seconds since the last
# message received from the daemon. If keepalive_interval is set to
# -1, qemu driver will not send keepalive requests during
# peer-to-peer migration; however, the remote libvirtd can still
# send them and source libvirtd will send responses. When
# keepalive_count is set to 0, connections will be automatically

Copying the key file /usr/share/ qemu/bios. bin (which is a link to /usr/share/ seabios. bin) to a "non-system" directory enables generation of a valid, though incomplete apparmor definition
In order to support Virtio access, a second apparmor file was generated (copy the file libvirt- <uuid>. files as a starting point) and added as an entry in the master ie. libvirt-<uuid>
This resolevd the app-armor issues
