Redhat linux KVM Virtual Machine bridging

Redhat linux KVM Virtual Machine bridging configuration bridge access method www.2cto.com. 1. Create a Bridge under the/etc/sysconfig/network-scripts directory and create a ifcfg-br0 file whose type is set to Bridge: Example: DEVICE = br0BOOTPROTO = staticBROADCAST = broadcast = 255.255.255.0NETWORK = 192.168.110.0ONBOOT = yesGATEWAY = 192.168.110.1TYPE = Bridge2. Bridge the physical interface to the bridge adapter to modify eth0 content (the server uses eth0 for Internet access ), remove the IP address information and add "BRIDGE = br0" to connect it to br0. If it is a dual or multiple NICs, modify the process as follows: DEVICE = eth0 # BOOTPROTO = static # B ROADCAST = 192.168.110.255HWADDR = 00: 30: 48: F1: 7C: 3A # IPADDR = 192.168.110.205 # NETMASK = 255.255.255.0 # NETWORK = 192.168.110.0ONBOOT = yes # GATEWAY = 192.168.110.1 # TYPE = EthernetBRIDGE = br03 restart the NETWORK service of the physical machine www.2cto.com [root @ virt ~] # Service network restart: closing the interface br0: [OK] Closing the interface eth0: [OK] Closing the loopback interface: [OK] pop-up the loopback interface: [OK] pop-up interface eth0: [OK] br0: [OK] 4. view the current bridging status [root @ virt ~] # Brctl show5: bridge the virtual machine interface to the bridge brctl delif virbr0 vnet0 brctl addif br0 vnet0 [root @ virt ~] # Brctl showbridge name bridge id STP enabled interfacesbr0 8000.003048f17c3a no eth0 vnet0virbr0 8000.000000000000 yes
