kvm-15 has a bug where it succeeds in initializing the module but 
returns failure.  So the filesystem is registered, module loading fails, 
and when you reload the module it can't register the filesystem again.

The fix was posted in 
http://article.gmane.org/gmane.comp.emulators.kvm.devel/1537.  I'll 
release kvm-16 shortly so others don't trip over it.
