[Xen-devel] Need help getting http interface with Xen 3 working
I''m trying to get the http interface working w/ Xen 3.0 and am running
into some problems. I know that in 3.0, twisted is no longer being
used for the http front end (using Apache w/ mod_python instead).
I''ve read Tom Wilkie''s post
(http://lists.xensource.com/archives/html/xen-devel/2005-09/msg00081.html)
on how he''s modified things to work under Apache, and it''s got
me a
bit further, but now I''m stuck. Here''s what I''ve done
do far:
I''ve installed Fedora Core 4, and set up Xen according to the
FedoraXenQuickStart guide (which tracks xen-unstable) at
http://www.fedoraproject.org/wiki/FedoraXenQuickstart . My dom0 kernel
boots nicely, and I can issue commands with the "xm" command.
I have mod_python installed and working for Apache 2 (I''ve tested it
with a simple program).
I''ve symlinked /var/www/html to /usr/lib/python2.4/site-packages/xen/sv
I think I have to modify my Apache config to include the something
like the following:
<Directory /var/www/html>
AddHandler mod_python .py
PythonHandler ?????
PythonDebug On
</Directory>
My (obvious) question is how to I properly wire up Apache/mod_python
to the correct file so I can query/change my Xen configuration via
http?
Any help appreciated. Thanks!
Jerry

I haven''t looked at SV for what must be a month now, some there is prolly some code rot in there. If I get a chance I''ll give it a quick check. Also its not that functional atm ;-) Cheers Tom> Any help appreciated.

Re: [Xen-devel] Need help getting http interface with Xen 3 working
Thanks, that''s the piece I was missing. I was trying to get mod_python to call the .sv/Main.py file directly (which I managed to do), but, obviously, it was also the wong thing to do :-). I made the appropriate change to my http.conf, pointed it at a copy of tools/index.psp and got further. Now I just need to figure out why I can''t get any node info (Xend is running, as I can execute "xm list" just fine). Is there any logging I can turn on to see where it might be getting stuck?
