That makes sense. I think the intention here is to use udev if it is version
059 or greater, or to use the older hotplug approach otherwise. Your system
should be using hotplug, in that case. From the log message below, it looks
like your hotplug is OK, since the vif-bridge script is running.

So this line here says that we have failed to add the vif to the bridge. Do
you intend to use bridged networking? If so, is the bridge up? You can check
using brctl show.
Usually, your bridge would be brought up by the network-bridge script, which
would be run by xend at start-of-day. This is configured in
/etc/xen/xend-config.sxp, in the network-script option. If you are using this
option, then presumably the network-bridge script is failing.
You can run the network-bridge script manually like this:
/etc/xen/scripts/network-bridge start
and then check your /var/log/messages for error messages again.
The network-bridge script has a few options. These are discussed in the Xen
distribution's example xend-config.sxp.
