  Hum, that seems to indicate that the cim-server found the schemas
describing the virt: namespace and that particular KVM entry point,
but it failed to find it in the dynamicaly loaded shared library set
which is exposed by libvirt-cim and implementing the given entry points.

  First suggestion would be to check for SELinux possible errors, since
sblim-sfcb might have troubles loading the shared library if the policy
is not directly helping. A second possibility might be that sblim-sfcb
is not finding the .so, and an strace of the daemon from the start may
show up in what directories it may be looking and if that correspond to
libvirt-cim .so installed paths.

  SELinux logs and strace :-\
