Xen community - Jul 2009 - Nothing major left to do in Xen Networking ???

Hi all,
       Is there nothing interesting left to do in Xen networking ?
Please give me pointers as to what is going on in Xen Networking.

Regards,
Leena

I just needed some good long term projects to work on
to share some of my code to Xen. But, I am not finding any
Xen Networking TODO list nor I am finding any papers with
new Ideas to Xen Networking. Can experienced Xen ppl please
guide me.

Regards,
Leena

Hi,

I''m also interested in network programming and Xen, and in fact I
already have a project of my own that I''d like to get people involved
in. If you are interested, the project is LiSA - http://lisa.ines.ro
and it already features basic xen integration.

It''s been no longer than a month since I posted on xen-users and
I''ve
got very little feedback. It seems to me that xen users are happy with
what''s already there in xen networking and are more concerned about
testing / running various guest operating, hardware, setups, etc.

Cheers,

Radu R.

The problem with getting feedback like this may be that Xen networking
isn''t perfect, but works well enough that there isn''t a great
deal of
interest in improving it.

Speaking for myself however, I''d be interested in hearing about any
efforts to get RSTP working with the Linux bridging driver, LiSA, or any
software bridge implementation.  We''ve been experimenting with
configurations involving Ethernet bonding vs. bridging, and the main
disadvantage I see with bridging+STP is the time it takes to discover
and react to a topology change.

This is exactly what I meant in my former message, but you put it in
better words :)

LiSA main (git) branches are still maintained by the original project
authors. However, we are constantly encouraging young students to
contribute to the project and at the same time improve their programming
skills.

This year we have had two academic projects involving RSTP and bonding
support for LiSA. I''m sorry to disappoint you, but the projects are not
yet complete and/or suitable for production use. Working with students
has proven to be a slow and tedious path towards adding more features to
the project.

Our primary goal however is to make the project known to people and to
create a user community. Then it would be easier to find people
interested in production use and financing the development of certain
features.

Last but not least, I kindly thank you for your feedback and promise to
keep you updated regarding RSTP support in LiSA.

Best,

Radu Rendec

if you are looking for a project, well a while back Cory Wallenstein
posted some patches to do IPv6 antispoof, to lock down mac addresses, 
and to do some inbound filtering for privacy (so you couldn''t see
traffic
that wasn''t addressed to you, something customers complain about.)

http://www.standingonthebrink.com/index.php/ipv6-ipv4-and-arp-on-xen-for-vps/

- I''ve been talking about trying to get them pushed upstream into the
xen.org
distribution for some time now, but I haven''t had the time.
