I reproduce the same on 18.04 LTS:
Log when starting a KVM VM with 'virt-manager':
--
Error starting domain: internal error: Process exited prior to exec: libvirt:

But the AppArmor profiles exist:
--
$ sudo ls -lah /etc/apparmor.d/libvirt/libvirt-*
-rw-r--r-- 1 root root 293 août 16 23:04
/etc/apparmor.d/libvirt/libvirt-a1937a46-2b13-41bd-998b-27ee9a8209a8
-rw-r--r-- 1 root root 1,8K août 16 23:05
/etc/apparmor.d/libvirt/libvirt-a1937a46-2b13-41bd-998b-27ee9a8209a8.files

I checked paths the VM relies on (CD-ROM ISOs absolute paths) and they
contain no whitespaces.
Tell me if the virt-manager VM XML file is needed for troubleshooting.
A troubleshooting sequence I tried, with no positive result:
1/ Deeply-deleting '*ibvir*' in '/etc/apparmor.d'
2/ Reinstalling the 'libvirt-bin' and its dependencies (incl.
'libvirt-daemon-system'), by providing the 'confmiss' DPKG flag: it restored
anything libvirt-related in '/etc/apparmor.d'
2.b/ Did 1/ and 2/ for the 'qemu-kvm' and 'virt-manager' packages also
3/ Reloaded the 'apparmor' systemd daemon
4/ Rebooted machine
5/ Reloaded daemons ('daemon-reload'), the 'libvirtd' and 'qemu-kvm' systemd
daemons
6/ Retried to start the VM
Could a dependency package be the cause of it?
