Bind a physical NIC to a Xen bridge in Linux

The Xen virtual opportunity defaults to bind the network adapter to the XENBR0,

So if you need to switch to a different physical NIC, you need to configure the script or execute the command yourself.

1. Add Script Bindings

A. Write a script that specifies the relationship of the NIC to the bridge binding

# Vim/etc/xen/network-wrapper

#!/bin/sh/etc/xen/scripts/network-bridge [email protected] vifnum=0 netdev=eth1 bridge=xenbr0 #... Multiple bindings can be added

B. Edit/etc/xen/xend-config.spx

Comment out (network-script Network-bridge)

Add (Network-script network-wrapper)

C. Restart the Xend service

# Service Xend Restart

2. Direct execution of command bindings (temporarily valid)

# cd/etc/xen/(not exactly remember ...) )

#./network-bridge vifnum=? netdev=eth* bridge=xenbr* Start/stop

Warning: Do not bind two physical network cards to the same bridge! Failure to do so will cause a network loop.
