I think the assumption here is that if you install a recent libvirt you
also install a recent QEMU. You always have the risk of things not
working if you have too old a QEMU, right?
Libvirt exists for providing back-compat glue. The following
combinations are supported:
old libvirt, old qemu
new libvirt, old qemu
new libvirt, new qemu
and it is only this combination that might require a libvirt upgrade to
work correctly:
old libvirt, new qemu
