It doesn't solve the problem for existing libvirt installations. It's
not uncommon for users to track just the latest kvm releases without
upgrading libvirt: any future qemu or kvm release will break every
version of libvirt that exists today. Given that unfortunate case, I
still recommend reverting the 'PC' change at least for long enough for a
few fixed libvirt releases to make it into the wild.
