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=6,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 - modprode bond0

7 - more /proc/net/bonding/bond0

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

about config i did for my xen kernel rhel 5.3 after i reboot the host server i get in place bond0 get pbond0 and its get disconnect from network only i ping to my vm's on the host server any one have any idea why xen bond0 is acting like that or what is solutions to come out of pbond0 to bond0.

Currently running Exchange Server 2003 Enterprise Edition on an HP 380 server, we would like to migrate to a new Dell 2950. Do I have to install from scratch or do I have a choice?

I also need an Active Directory domain controller.

Is there a tool which I can use for the same copy and paste on the new hardware?
