Re: [Xen-users] New to xen, difficulty getting network going
I'm running Xen on Etch. I needed to do the following...
1) Uncomment the following line in /etc/xen/xend-config.sxp ...
(vif-script vif-bridge)
2) In the DomU config file ensure you have the following...
vif = ['bridge=xenbr0']

I used to get this .. from memory there are some networking scripts
under /etc and one of those had to be started/restarted. You might then
run into further problems with Etch, someone recently posted a 4 step
plan to working with Etch, but using Xen from unstable. So long as you
remember the final step of copying kernel modules to the DomU it works
very well!
Searched for that 4-step plan but did not find it. My problem may be
related to the fact that Debian does not run the bridging scripts by
default when starting xend. So I'm going to enable that and see what
it says. Also, I'll read those scripts. I suspect that there's a lot
to be learned from them.
Thank you!
