ACK. 

BTW, how exactly are you getting all these warnings/diagnostics ?
Are you merely compiling libvirt using clang & just collecting
the warnings, or is this some special static analysis tool ?

If we're going to start adding these non-null attributes, then 
I should hook the appropriate tool into autobuild.sh to validate
them regularly.
