I think that's going to lead to even more confusion.  While I'm inclined 
to not greatly mind 0.10.99 for the development tree, when we do release 
candidates for the next release, it's going to be 0.11.0-rc1.  I don't 
expect RPMs to ever be created from non-release versions of QEMU 
provided we stick to our plan of frequent releases.

I still think libvirt should work with versions of QEMU/KVM built from 
svn/git though.  I think the only way to do that is for libvirt to relax 
their version checks to accommodate suffixes in the form
