Masquerading local broadcast breaks DHCP replies for some clients.
There has been a report about broken local multicast too.
(See references in the patches.)

Testing: since I have no idea how to test upstream libvirt on a
RHEL-6.4.z virt host and guarantee nothing will be tangled up, I ported
the series to libvirt-0.10.2-18.el6_4.5 and tested that. (The upstream
series does build and passes the checks in HACKING, except I didn't try
valgrind.)

Laszlo Ersek (2):
  util/viriptables: add/remove rules that short-circuit masquerading
  bridge driver: don't masquerade local subnet broadcast/multicast
    packets
