Re: Is ixgbe usable with SR-IOV?
Unfortunately its a feature that was implemented, and worked, but it has not had a lot of use I suspect, and it has been in a limited number of setups. I know nothing about this Amazon provided hosting, is it linux/kvm or xen? I can see if we can get something set up and check it here.

Re: Is ixgbe usable with SR-IOV?
OK, very different kettle of fish from anything that's been tested :) Let me talk about it with some people tomorrow and see what we can do.
