The security manager drivers are not allowed to call back
out to top level security manager APIs, since that results
in recursive mutex acquisition and thus deadlock. Remove
calls to virSecurityManagerGetModel from SELinux / AppArmor
drivers

The patch causes the following warning:

I switched off warnings and compiled libvirt with the patch anyway,
and it fixed the problem for me (both libvirtd not being able to be
killed, and libvirtd not starting up the libguestfs appliance).
Thanks, Rich.
