Bonding with xen

1 - Stop all guests. Reboot dom0 after running "chkconfig xend off" and "chkconfig xendomains off".
2 - Configure bond0 by enslaving eth0 and eth1 to it. I added the below two entries to /etc/modprobe.conf.

alias bond0 bonding
options bond0 mode=1,miimon=100

Content of /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

Content of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

Content of /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0
IPADDR=
NETMASK=
ONBOOT=yes
BOOTPROTO=static
USERCTL=no

Did "modprobe bond0" and "service network restart" after that.

3 - Edit /etc/xen/xend-config.sxp

Change

(network-script network-bridge)

To

(network-script 'network-bridge netdev=bond0')

4 - Start xend. "service xend start".

5 - chkconfig xend on.

6 - Create guest images as usual and bridge it to xenbr0.
