Thanks to both of you guys for helping me out with this! I think I've gotten the idea and now have eth0 up and functional in the way you described! However, I realized that there is one additional thing that I would like to do and that is have eth0 and eth1 bonded together and have the Xen machines use that bond just like they are currently using the eth0 device. I tried doing this in the way that I normally would, bonding them together, however, it didn't seem happy afterward. Have either of you guys done that and if so are there some gotchas I might have missed? Either way, thank you so much for helping me out with this and explaining it! It is very much appreciated!

Mine mostly looks something like this after removing the VLAN trunk complication: # cat ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes BRIDGE=br6 # cat ifcfg-br6 DEVICE=br6 TYPE=Bridge BOOTPROTO=static ONBOOT=yes IPADDR=10.10.6.1 NETMASK=255.255.255.0 NETWORK=10.10.6.0 BROADCAST=10.10.6.255 Now your primary IP of your dom0 lives on the br6 interface. Your domU's will be on the same VLAN and should see your DHCP server. Don't forget to enable IP forwarding. # grep phys /etc/sysconfig/iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT # grep forward /etc/sysctl.conf # Controls IP packet forwarding net.ipv4.ip_forward = 1 p.s. use 'brctl show' to see your bridges. -- Dale Bewley - Unix Administrator - Shields Library - UC Davis GPG: 0xB098A0F3 0D5A 9AEB 43F4 F84C 7EFD 1753 064D 2583 B098 A0F3 ************************************************************************ **** Checked by MailWasher server (www.Firetrust.com) WARNING.
