Perhaps something could be added to /etc/libvirt/qemu.conf, alongside the user/group settings that qemu will run under. Also, when using 'virsh save' followed by 'virsh restore', libvirt ensures that the restore will (temporarily) change permissions as needed on the file to be legible by qemu even if the save file didn't have those permissions.
