I'm puzzled by why I'm the only one seeing it as well.  One difference 
may be that I seem to have compiled --with-uml.  I'm not sure if that's 
the way most people are doing things; it's just what I get from 
autobuild.sh on my box.

I'm still tracking down an unresolved issue on my setup during the 
daemon-conf scripts, which is that libvirtd is getting farther into 
running during the corrupt configuration tests than Jim thinks it 
should.  I'll take a look to see if that is the reason for this behavior 
as well.
