Can you tcpdump on bond0, br0, vnet0, and the guest's interface to see

Sure. Using the tcpdump command line:
tcpdump -i br0 -w /var/tmp/tcpdump.br0 ether host 00:16:36:2f:f1:d2
(similar for other interfaces) I can see the DHCPOFFER coming
from my dhcp server on bond0:

It is also visible on br0:

But it is not visible on vnet0, and of course not on the
guest. All I see there are the DHCPDISCOVER calls sent by
the guest, and some IPv6 traffic:
So, it looks like a bridging problem. Can you send this the bridge
maintainers (Stephen Hemminger <shemmin...@linux-foundation.org>,
bri...@lists.linux-foundation.org)?
