Thanks Tom for the info, I had remembered twisted being removed but
hadn't realized that XenSV had been since updated. A couple
questions though...
Why not decouple the interface from Apache (as to require only
python be installed)? I am not sure of the performance advantage,
but it should reduce the memory requirements for dom0, allow for a
slightly smaller disk (negligible), and make installation easier.
Well, I didn't want to completely re-implement a HTTP server
(although I suppose its not tough) so I looked at using another one.
The bit that depends on apache/mod_python is minimal, about a 20 line
adapter between mod_python and what twisted used to provide. So if
you wrote your own http server it would be a reasonably straight
forward task to do.
I might actually do this, the dependance on apache is a pain, and I
think xend has its own http server in it atm.
Similarly have you looked into writing XenSV in C?
The primary reason I choose python is because thats what we use in
cambridge, and its what all the other tools and written in ;-) Also
it lets me call straight into the XendClient.py stuff, which
simplifies it greatly.
Finally, is there any distributed computing tools for Xen, ie, a
controller software? This is where my interest really lies, as I
am working for a group that could use a tool like this and am also
looking for a way to get involved.
I seem to remember somebody talking about one, I'm sure somebody else
on the list will be able to respond to that. If not I'll ask about on
monday.
I haven't had an oppurtunity yet to install apache, but will be
doing so soon enough.
The mod_python website has all the info on getting psp up and running
quickly, just three lines in a config file worked for me.

David

Dear David
The web based front end, XenSV, is still alive and kicking in the
latest unstable. I did some work on it a few weeks ago, removed
its dependancy on twisted, and made it run using mod_python, and
apache. I'm planing on doing some more work on it in the coming
weeks, and doing a howto for installation.
SV works by calling into the XendClient.py file, the same file xm
uses to communicate with Xend. Its is written entirely in
python, which probably isn't the best choice for a web app, but
makes it easier to interface with xend.
Cheers

Hello all,
I was curious if there is a web based front end (or one in the
works) for xen-unstable. Last I checked, the built-in one for
2.x was being tossed out. Secondly assuming that there isn't
one, would the preferred language be python? Finally, would it
be better to be a front end for xm or would it be better to
more tightly integrate it (or of course the mix)?
Thanks,
David
