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:

SCRIPT=/bin/false if [ -r $CONFIG_FILE ]; then SCRIPT=$(sed -e '/^[^#]*vif-script/!d;s/^(vif-script *\([^ )]*\)).*$/\1/' \ $CONFIG_FILE) fi

if [ -z "`which $SCRIPT`" ] ; then # not in path, should probably log an error exit fi

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
problems...

Right.

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

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 :(.

thanks, Nivedita
