I was almost going nuts with qemu/virt-manager. I could no longer attach USB devices to the guest. When shutting down the guest, it ended up in a "shutting down" state, and never exited from that. Then I found a post [1] pointing the finger to apparmor. I uninstalled it and everything works again as expected. At the moment I have no plan to reinstall it.
