I've spent the past few months dealing with customers using the 
libvirt/qemu/kvm stack.  Usability is a major problem and is a top 
priority for me.  That is definitely a shift but that occurred before 
you started your thread.

But I disagree with your analysis of what the root of the problem is.  
It's a very kernel centric view and doesn't consider the interactions 
between userspace.
