Xen: Change bridged ethernet interface for xenbrX (CentOS 5.x)
If you need to change the Xen DomU from routing through EthX to EthY edit your /etc/xen/scripts/network-bridge and change “vifnum=${vifnum:-1}” to “vifnum=Y”. Then edit the DomU xm config file located in /etc/xen/ and change the “bridge=xenbrX” to “bridge=xenbrY” on the “vif=” line.
NOTE: This was done under CentOS 5.x using Xen 3.0.3.
