[Bug 785668] Re: bonding inside a bridge does not update ARP correctly when bridged net accessed from within a VM

[Serge Hallyn]

Following the advice toward the bottom of

http://forum.proxmox.com/archive/index.php/t-2676.html?s=e8a9cfc9a128659e4a61efec0b758d3e

I was able to get this to work with balance-rr by changing a few bridge
properties.  The following was my /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto bond0
iface bond0 inet manual
 post-up ifconfig $IFACE up
 pre-down ifconfig $IFACE down
 bond-slaves none
 bond_mode active-rr
 bond-downdelay 250
 bond-updelay 120
auto eth0
allow-bond0 eth0
iface eth0 inet manual
 bond-master bond0
auto eth1
allow-bond0 eth1
iface eth1 inet manual
 bond-master bond0

auto br0
iface br0 inet dhcp
 # dns-* options are implemented by the resolvconf package, if installed
 bridge-ports bond0
# bridge-stp off
# bridge-fd 9
# bridge-hello 2
# bridge-maxage 12
# bridge_max_wait 0
 bridge_stp on
 bridge_maxwait 0
 bridge_maxage 0
 bridge_fd 0
 bridge_ageing 0

I don't know if this is acceptable to you since stp is on.  If not, is
using balance-alb (which did also work for me) acceptable?
