What command line did you pass to configure?  AppArmor is optional (and
in fact, Fedora does not use it); so this message should only be
triggered if you passed an explicit --with-apparmor or
--with-secdriver-apparmor to configure, in which case, yes, then you
need the apparmor devel package.

This usually means that qemu failed to start; can you check the log file
for that guest (perhaps /var/log/libvirt/qemu/xpSP3.log) to see if there
are more details why?
