Xen users - Dec 2010 - netchannel2 - how to use and configure?

So supposedly one of the new features in xen4.0 is netchannel2.  However I
can''t find any documentation on how to configure it or what is required
to
use it?

I have found snippets of things like you have to specify vif2 = in the xen
cfg file but that is about it.

I''m using the latest pvops kernel with latest xen 4.0.1 mainline.

Do I need to build the kernel with specific CONFIG options?
Will it just work with any domU or does it need updated pv drivers?  Right
now I''m trying to boot a rhel5 domU.
Can anyone give me all the options I can specify with it in the xen cfg
file?

Thanks,
Tom

Anyone??  Seems a shame to have this listed as major feature in xen4.0  but no
info on it.

Thanks
Tom

Afaik netchannel2 stuff was never ported to pvops 2.6.32.x kernel.

(or actually, Jeremy has the patches, but noone has asked him to
to put them on his kernel trees.)

It seems there''s no maintainer for netchannel2 stuff atm.
There was some discussions about it a couple of months ago on xen-devel.
