** Description changed:

+ ===========================================
+ Impact: cannot start libvirt-qemu VMs on ppc64el
+ Test case: See below in the description.
+ Regression potential: this debdiff only adds apparmor permissions which are already being granted in vivid, so no new regressions should be possible
+ ===========================================
