Re: [Xen-users] New to xen, difficulty getting network going

[Simon Capstick <simon@xxxxxxxxxxxxxxxx>]

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']
