Actually I've had this problem too, on Gentoo, which comes more or less with no packages preinstalled. My network scripts was failing silently too and as the server was in colo, the quick solution I found was to bring xen-br0 up manually with: ifconfig eth0 0.0.0.0 promisc up brctl addbr xen-br0 brctl setfd xen-br0 1 brctl sethello xen-br0 1 brctl stp xen-br0 off brctl addif xen-br0 eth0 ifconfig xen-br0 ................. up route add default gw ...................Actually I had very bad problem with machine dropping packets in peak hours /~10Mbit network traffic from pages, no big downloads/. I was seening: Feb 13 22:36:58 carrier ip_conntrack: table full, dropping packet.in the kernel log all the time, also netstat was reporting many times more open connections that was the number of apache processes. I've found that there is a bug in connection tracking code, introduced in 2.6.10 /not sure, but was a recent bug/, I've found a patch for this problem, but I was not feeling like patching, recompiling and rebooting in peak hours, so I've solved the problem with: echo 131072 > /proc/sys/net/ipv4/ip_conntrack_max Hope this helps somebody.Also does anybody here know about this problem and if it is fixed in xen 2.0.5, as it is 2.6.10 based too?

Make sure you have it by installing the package iproute.
