Re: KVM+FreeBSD+82599 10G NIC doesn't work.
The environment that I tested in when the virtualization support was put into the driver was using SRIOV, not pass-through, we have never validated the latter, and whenever it crops up it seems to be having problems. I can put it into my queue to look into, but I can't say how quickly I can get to it, very busy here.

Re: KVM+FreeBSD+82599 10G NIC doesn't work.
Thanks a lot Jack. According to my test, SRIOV works fine! It's not the way we want, but this solution really helps. So, we'll spend more time to solve the real problem, while we can use SRIOV as a substitution. -- Best wishes.
