[Xen-devel] Fwd: xend, network-script and vif-script

["Henning Sprang" <henning_sprang@xxxxxx>]

Hi xen-developers,
I didn't get any hint to this question from xen-users, but I am sure,
you know how I get to see the output (e.g. things printed with echo
for debuggin purposes) of the scripts I define as network-script and
vif-.script somewhere - do you?

Below a longer explanation, if you are interested.

Hi,
For a custom network setup, I want to modify the default
network-script and vif-scripts. So I made a copy of them and changed
the config in xend-config.sxp to use the copies which I want to
change.

Then I started adding my own features in the start and stop sections
and see what they do.
As they don't do immediately what I want (oh, wonder?!  ),  I realize
they are hard to debug:
The problem I have here is that I don't see where the output of these
scripts is written to for debugging and tracing purposes - no logfile
seems to contain stuff I echo from there, and no console.
Is there any configuration option to enable seeing more output from
these scripts? I cannot find any documentation for that, loglevel is
set to DEBUG in xend-config..sxp

Then I wondered if it's right that the network-script is actuall never
called with stop as argument, while I would assume it will be called
when running xend stop.

I already started to read through the python code, because I didn't
find any other information, but this will take some time until i
understand all the xend python code - maybe somebody has a hint?

Henning
