4.5 is not yet released (we've had 4.5.0-rc2 so far). Any moving to using it should bear that in mind. Of course we always welcome testing of release candidates, but you should be aware that they are candidates, not releases. IMHO it is very unlikely that systemd support or RPM packaging will make any different to passing more than 4 bridges to the guest. My guess is that you are ending up with emulated devices and that qemu has a limitation. See http://lists.xen.org/archives/html/xen-users/2014-11/msg00062.html Ian.
