I dont have any raids configured at my laptop but had on my production server and the reason, the reason why i've installed kvm on laptop was that i was thinking that its raid problem :) and to reproduce (for me) only i've got to do is fresh ubuntu installation with kvm. i dont know, may be its up to my hardware specs and some of kvm / libvirt code part. but the patch u've provided seems to solve the problem. so there must be something in the changelog
