Mailing List Archive: traceroute causes xen reboot from virtual machines

Hi all,

I have successfully installed xen 2.0 on debain linux 2.6.10. I have
two methods to get networking done namely routing and bridging. I am
using UML (user mode linux) mode of bridging as the vif-bridge was not
working for me. It was cutting off my Domain 0 connection from
internet when i start the vif-bridge. Anyway this is what i did to set
up the bridge.

host# brctl addbr br0

host# ifconfig eth0 0.0.0.0 promisc up

host# ifconfig vif1.0 0.0.0.0 promisc up

host# ifconfig br0 192.168.0.1 netmask 255.255.255.0 up

host# brctl stp br0 off

host# brctl setfd br0 1

host# brctl sethello br0 1

host# brctl addif br0 eth0

host# brctl addif br0 vif1.0

and bridge is successfully setup.. Now the problem starts... if i run
traceroute from Domain 1,2.. (child domains) linux BOOTS !!!

please look into it.

I know that i shud be using the bridge provided along with xen
(somehow that too isnt working) but UML method of bridging is equally
valid.

thanks in advance

Please upgrade to a more recent version of Xen e.g. 2.0.3

traceroute works fine for me.

Are you sure its not the default 'network' script that is causing you
problems rather than vif-bridge?
