Public bug reported: I'd like to emphasize that I upgraded from Ubuntu Gnome 14.4 to 14.10 I installed systemd.
libvirtd fails to start on the stock upgrade system. Examining the log files it looks like apparmor prevents libvirtd from creating a net socket. Okt 28 00:31:49 rivendell kernel: audit: type=1400 audit(1414452709.808:42): apparmor="DENIED" operation="create" profile="/usr/sbin/libvirtd" pid=15162 comm="libvirtd" family="netlink" sock_type="raw" protocol=9 Okt 28 00:31:49 rivendell kernel: audit: type=1400 audit(1414452709.808:43): apparmor="DENIED" operation="create" profile="/usr/sbin/libvirtd" pid=15162 comm="libvirtd" family="netlink" sock_type="raw" protocol=0 I tried to run aa-logprof in order to have apparmor fix the permissions but that did not work. that is why modified apparmor profiles are attached. Putting apparmor in audit mode aa-audit /usr/sbin/libvirtd enables me to start libvirt systemctl restart libvirtd It looks like the apparmor profile permissions have to be adjusted.
