Hi. We chatted a while back about IB, and you explained your IPoIB setup,
and indeed you released your whole solution to the community. That was a
very cool thing to do.

I'm wondering how you arrived at your solution, because I wonder if I'm
barking up a tree you've already determined has no cats... :)

Was using IPoIB the initial goal, or did you try other methods before
settling on this one? I ask because the tack I'm taking is to try to use
iSER. After reading a lot more about how ONE works, it *seems* like it
should be pretty easy (knock on wood). It seems like with tgtd (which
luckily has iSER support built-in), it should essentially be transparent,
as long as the initiator in the host is iSER aware as well. It almost seems
like the iscsi method out of the box should 'just work'. Or, am I dreaming?
:)
Did you experiment along this vein?

It would be greatly simplify the network configuration as well if it did
work, because there would be no need for the NAT rules anymore - the guest
would use OVS in the host for their networking.

Anyway, I'm going to try that (unless you've already tried tried it to no
avail) first, and I'll let you know how it goes.



Regards,
Christopher Barry
