Hi, I am using the latest xen-unstable by Jul. 15th. Everything is dom0 works fine. But as soon as I input 'xend start', all the network connections just die. I am using Broadcom NetXtreme network card, with tg3 driver. I have collected some basic information and post it in the following part. I remember some one seems to meet the same problem before, and I try to find the solution is that thread, but no luck. Could anyone give any help? Thanks. ====================================================================== Result for ifconfig: BEFORE xend start: eth0 Link encap:Ethernet HWaddr 00:0D:60:9A:15:60 inet addr:9.2.72.112
