Bug Description

/etc/apparmor.d/usr.lib.libvirt.virt-aa-helper uses abstractions/base which has the following:
  owner @{HOME}/.Private/** mrixwlk,
  owner @{HOMEDIRS}/.ecryptfs/*/.Private/** mrixwlk,

This may be too strict for virt-aa-helper since it runs as root and user's may store there VMs in encrypted HOME or encrypted ~/Private with the files owned by the user, not root. The following should be added to /etc/apparmor.d/usr.lib.libvirt.virt-aa-helper:
  @{HOME}/.Private/** mrixwlk,
  @{HOMEDIRS}/.ecryptfs/*/.Private/** mrixwlk,

Reducing to low. The files are still allowed access by the VM, so the apparmor denied message is more confusing than anything else.
