[ubuntu] virtual machine in bridge mode

view full story

http://ubuntuforums.org – I created two KVM virtual machines VM1 and VM2 in bridge mode. The brctl and ifconfig info in the following shows the br0 and vnet0/1 interfaces. But only vm2 respond to arp request but not vm1. Any specific configuration for multiple virtual machines in bridge mode to work? Thanks in advance. --- br0 Link encap:Ethernet HWaddr e0:db:55:93:76:40 inet addr: Bcast: Mask: inet6 addr: fe80::e2db:55ff:fe93:7640/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:858634 errors:0 d (Hardware)
