I think perhaps we should make this a QEMU driver config option (ie be
in /etc/libvirt/qemu.conf) and have 2 flags 

  security_driver="selinux|none"
  security_autolabel="yes|no"

If security_autolabel is set to 'no', then the app must pass an explicit
security context in the domain XML, otherwise the domain is unconfined.

If security_autolabel is set to 'yes', then if the app passes an explicit
security context this is used, otherwise it will auto-generate one at
startup of the VM.

Regards,
Daniel
