Re: [Xen-users] DomU WinXP no network connection

[Tiziano Mueller <tiziano.mueller@xxxxxxxxxxxx>]

Well, I don't want xen to create any bridges or network-devices itself,
so I wrote a new vif-* and a new network-* script to achieve that (using
Gentoo Linux).

The network-* script is empty except for a line containing "/bin/true"
and the vif-* script contains the following:


******************************************
dir=$(dirname "$0")
. "$dir/vif-common.sh"


case "$command" in
    online)
        /etc/init.d/net.${vifname} start
        ;;
    offline)
        /etc/init.d/net.${vifname} stop
        ;;
esac

success
******************************************

The following line is important in the configuration-file for the
virtual machine:

******************************************
vif = [ 'type=ioemu, vifname=vifwinxp, bridge=br0' ]
******************************************

In addition to that, I create the bridge 'br0' manually (with an IP) and
attach a real ethernet device (lan0) to it:


******************************************
# brctl show

bridge name     bridge id               STP enabled     interfaces
br0             8000.0017312c5aaa       no              lan0
                                                        tun0
                                                        vifwinxp
******************************************


(I didn't test it yet, but it's probably not even necessary to create
the device 'vifwinxp', since xen creates a device tun0 for the virtual
machine.)
... and don't forget to change the names of the network scripts in
/etc/xen/xend-config.sxp if you create new vif-* and network-* scripts
and restart xen to load it.
