I’ve been running HA on CentOS 7 and then migrated to a Dell server running Fedora Server 32 and using KVM and Docker. The supervised install script worked flawlessly each time, only warning me about AppArmor missing.
I tried to create a new VM with Fedora Server 32, all latest updates applied. When I ran the HA install script, it failed on AppArmor missing. I changed the script to switch AppArmor from error to warn. Reran the installer and it ran fine. No issues with HA and it’s running fine.
This was a rather lengthy way to ask why is AppArmor needed for the supervised install on generic linux? For over a year, HA has performed flawlessly without AppArmor.
Also, I’ve tried to use the QCOW2 vm file on my server. When I import it using Cockpit, it has to know what OS am I installing. Generic Linux isn’t an option. What should I use if I want to try out the QCOW2 file?
