I have a hp microserver gen 8 and i successfully passthrough this nic to 4 vms in unraid . Problem is, it seems it only gives 2 mac addresses. Is it because it has 2 network chips?

 

I thought a 4 port nic would have a diferent mac address on each port.

 

I discovered this after 2 hours of loop reconfiguring my switch, to realize host was flapping between ports....

 

Thanks!

    Don't know anything about the card, but I was wondering if you could spoof/re-assign the MAC address inside your guest OS and if that would work?

    I am not familiar with this card, but it is wrong design to use duplicate MAC addresses. Have you asked HP?
