[Xen-API] XCP 1.1 OVS and active-backup mode seeing traffic on both interfaces

[brooks@xxxxxxxxxxx]

I'm seeing traffic on both interfaces of an active-backup bond. This is a 
bond of eth0 and eth1 with both management and vm traffic.  Given the 
requirement that a bonded management interface be in active-backup mode 
and since balance-slb doesn't work unless the ports are connected to the 
same switch (or stack) I have the bond in active-backup mode:
# xe pif-list 
uuid=c5145148-5a9d-fe94-8129-d66fb26cb0f4 params=other-config
other-config (MRW)    : bond-mode: active-backup

It would seem like it's setup and working correctly with eth1 being the 
active interface. So, why am I seeing VM traffic on eth0?
# tcpdump -vv -i eth0

16:25:46.653749 IP (tos 0x0, ttl 245, id 40076, offset 0, flags [none], 
proto: ICMP (1), length: 84) 65.102.12.15 > vpc: ICMP echo 
request, id 27167, seq 18452, length 64
16:25:46.653805 IP (tos 0x0, ttl  64, id 31595, offset 0, flags [none], 
proto: ICMP (1), length: 84) vpc > 65.102.12.15: ICMP echo 
reply, id 27167, seq 18452, length 64
The problems I'm seeing are intermittent packet loss to both the VM and 
to dom0 as well as the interfaces being dead after a live migration until 
I send traffic from the VM.  This same environment works fine under 
XenServer 5.5 (running in linux bridge mode).  There's very little 
knowledge available in relation to OVS so any guidance would be 
appreciated.
