This is caused because the libvirt-qemu user is added to the nova group as part of the nova-compute-libvirt package post-install script.
Following up on comment #17 above, the user/group of the delta file changes from nova:nova to libvirt-qemu:kvm, whereas in comment #21 above, the user/group of the delta file changes to nova:kvm.
Dropping libvirt-qemu from nova in /etc/group fixes this as a work-around. I'm building packages with a fix now and will get this fixed for ussuri and victoria.
