@dkidd255 I'm a LOOONG time XCP/XenServer/XCP-ng user in my homelab...And it pains me to say this...
But this just works in Proxmox.
If you want to help us dig in and troubleshoot/explore this topic...Fine.
If you want to actually use your hardware and make progress on your ideas, go to Proxmox.
I seem to recall some recent firmware shenanigans from Intel. Intel maybe thought a little too much of their hardware, or they've decided to just scale things back a bit, but newer versions of firmware have reduced VF's available. I don't think the B70 is impacted by this, but it has massive memory in comparison to the smaller cards.
