# Clarify how to fix it #

Your rules out of logprof are interesting.

I have compared them with the one in the package in regard to unix/dgram rules which is what the denial is about. The only entry your example has on top is the following:

  network unix dgram,

Could you please try to:
1. revert /etc/apparmor.d/usr.sbin.libvirtd to the content delivered by the package in 20.04
2. retry and verify the issue triggers
3. restart libvirtd (systemctl restart libvirtd)
4. retry and verify the issue triggers still
5. add this line above to /etc/apparmor.d/usr.sbin.libvirtd where the other network rules are
6. sudo apparmor_parser -r /etc/apparmor.d/usr.sbin.libvirtd
7. restart libvirtd (systemctl restart libvirtd)
8. retry and verify the issue triggers still (or is it fixed now?)

#3 ensures that restarting the service without a change does not by accident resolve the issue
#6+#7 ensures that the apparmor profile with the change is reloaded and the rule is good

Please report how that test worked for you.
Hopefully that is the one entry we need, otherwise we need to continue looking for differences,
