There are several small daemons on a xen installation and the number of them is growing quickly.

However network-bridge is quite handy and simple to use, I think we should provide the users a simple way to automatically setup the network no matter what their distro is. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
