The immediate problem is in fact that vif-bridge is being called instead of vif-route.

I'm working on something like the following to detect the script:
if [ -r $CONFIG_FILE ]; then
    SCRIPT=$(sed -e '/^[^#]*vif-script/!d;s/^(vif-script *\([^ )]*\)).*$/\1/' \

As you can see, sxp is not very script friendly.

The above isn't going to be sufficient.

Having been able to call vif-route, is just the beginning of the real 


Once I'm in vif-route I need to get the IP address that I assigned to the 

Would have been nice to get some head's up on the hotplug
stuff going in so we could test for various networking situations.

To get that I need to figure out the domain id. (I suppose I could guess that from the device name.)

Then I need to find the SXP config file in xenstore (and now I need a
tool to parse it and extract the "(ip a.b.c.d)" statement), but I don't
see a way of doing that because there seem to be no scripting tools to
access xenstore.

We're trying to come up with a temporary hack to work around this
right now.

Now, even if I did have such a tool, I don't see a way of going from
domain id to uuid, which is what I think I need in order to interact
with xenstore.

Can't do it this way :(.
