Public bug reported:
This configuration seems to no longer work after upgrading a machine
from Ubuntu 18.04 to Ubuntu 20.04:
<seclabel type='dynamic' model='apparmor' relabel='yes'/>
When starting a domain with this configuration in the XML definition,
the following error appears and the domain fails to start:
error: unsupported configuration: Security driver model 'apparmor'
is not available
Is this to be expected? I wouldn't expect this on first glance because
the apparmor profiles are still included:
$ dpkg -S /etc/apparmor.d/usr.sbin.libvirtd
libvirt-daemon-system: /etc/apparmor.d/usr.sbin.libvirtd
$ apt-cache policy libvirt-daemon-system
libvirt-daemon-system:
Installed: 6.0.0-0ubuntu8.3
Candidate: 6.0.0-0ubuntu8.3
$ apt-cache policy libvirt-daemon
libvirt-daemon:
Installed: 6.0.0-0ubuntu8.3
Candidate: 6.0.0-0ubuntu8.3
$ apt-cache policy apparmor
apparmor:
Installed: 2.13.3-7ubuntu5.1
Candidate: 2.13.3-7ubuntu5.1
Files like /etc/apparmor.d/libvirt/TEMPLATE.qemu definitely do exist.
Am I missing something, is this a driver I need to install separately?
