Ok, I have definitely a snapshot left that has "conserved" the bad state.

I found that Focal no more could migrate to Groovy with: $ virsh migrate --unsafe --live fguest qemu+ssh://10.162.30.163/system error: unsupported configuration: Security driver model 'apparmor' is not available I looked after it and found that while all former releases detected apparmor correctly: $ virsh capabilities | grep -C 3 secmodel <cache> <bank id='0' level='3' type='both' size='15' unit='MiB' cpus='0-11'/> </cache> <secmodel> <model>apparmor</model> <doi>0</doi> </secmodel> <secmodel> <model>dac</model> <doi>0</doi> <baselabel type='kvm'>+64055:+108</baselabel> <baselabel type='qemu'>+64055:+108</baselabel> </secmodel> Now on groovy that didn't work anymore: <secmodel> <model>none</model> <doi>0</doi> </secmodel> <secmodel> <model>dac</model> <doi>0</doi> <baselabel type='kvm'>+64055:+108</baselabel> <baselabel type='qemu'>+64055:+108</baselabel> </secmodel> Since 3.0 is only in proposed: # apt-cache policy apparmor apparmor: Installed: 2.13.3-7ubuntu6 Candidate: 3.0.0~beta1-0ubuntu1 Version table: 3.0.0~beta1-0ubuntu1 500 500 http://archive.ubuntu.com/ubuntu groovy-proposed/main amd64 Packages *** 2.13.3-7ubuntu6 500 500 http://archive.ubuntu.com/ubuntu groovy/main amd64 Packages 100 /var/lib/dpkg/status I installed the former version. $ apt install apparmor=2.13.3-7ubuntu6 $ rm /var/cache/libvirt/qemu/capabilities/* $ systemctl restart libvirtd And it works again. Interestingly going back to 3.0 then works and keeps working. Therefore maybe it is a red-herring and I'll consider it incomplete & low prio for now until I know more (allowing others that might see the same to find this bug and chime in).
