In honor of Xen Doc Day, I've put up some basic HOWTOs for setting up bridging on CentOS 6 and 7. I'm far from an expert, so I'd appreciate any feedback.
The howtos can be found here:

If you'd like to extend that a little bit, here's example configs on how to do LACP and vlan tagging on c6:
host network-scripts # cat ifcfg-eth0 DEVICE=eth0 ONBOOT=yes USEERCTL=no BOOTPROTO=none IPV6INIT=no MTU=1500 MASTER=bond0 SLAVE=yes
host network-scripts # cat ifcfg-eth1 DEVICE=eth1 ONBOOT=yes USEERCTL=no BOOTPROTO=none IPV6INIT=no MTU=1500 MASTER=bond0 SLAVE=yes
host network-scripts # cat ifcfg-bond0 DEVICE=bond0 ONBOOT=yes USEERCTL=no BOOTPROTO=none IPV6INIT=no BONDING_OPTS="miimon=100 mode=802.3ad"
host network-scripts # cat ifcfg-vlan### DEVICE=vlan### ONBOOT=yes USEERCTL=no BOOTPROTO=none IPV6INIT=no PHYSDEV=bond0 VLAN=yes VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD IPADDR=10.x.x.x NETMASK=255.255.255.0 GATEWAY=10.x.x.x DOMAIN="example.com" DNS1=x.x.x.x DNS2=x.x.x.x DNS3=x.x.x.x
I use my own bridging control scripts, but this should extend your existing doc nicely just by using BRIDGE=xenbr0 in the ifcfg-vlan### file.
Also there's a small error in your c6 doc, you specify ifcfg-$dev but $dev never gets set anywhere.

Hey Nathan,
Thanks for the feedback. I meant the HOWTOs to be for a super-basic setup. I presume someone who wants vlans and what-not can read the full RHEL 6 / 7 documentation (which I linked to from the parent document, https://wiki.centos.org/HowTos/Xen/Xen4QuickStart.
If you want to add a new wiki page with your suggested setup, and link to it from the main page, that would be good as well.
Also there's a small error in your c6 doc, you specify ifcfg-$dev but $dev never gets set anywhere.
Ah, thanks -- missed that one when copy-and-pasting from my testing scripts. :-)
Peace, -George
