Re: [Xen-devel] [Xen-users] Problemi using vif-route script

I'm ccing xen-devel and Roger since he's been looking at the hotplug
stuff.

I didn't realise this was a feature of the old stuff, but yes I can now
see that tools/hotplug/Linux/vif-common.sh:dom0_ip() expects
netdev=<foo> to have been passed as a parameter to the script.

This something we should fix in the libxl layer I think. In the meantime
the obvious workaround would be to create vif-route-bond0 as a simple
wrapper around vif-route.

ip should be parsed and written to xenstore -- do you see it there (in
the backend dir)? I can see the code which reads it in the hotplug
script.

If the IP address is in xenstore then more verbose vif-route output
would be useful. I usually do

exec 1>>/tmp/vif-hotplug.log
exec 2>&1
set -x

at the top of the script..

Thanks,
Ian.
