Good day, 

 

as stated i have an issue where im trying to pass through a quad NIC to a VM

However when trying to pass the NIC through, it states 2 of 4 ports are being used by unraid

 

Any suggestions would be great thanks

eth0 is your main NIC, and eth1 is configured for DHCP, I don't see any extra NICs, what NIC do you plan to leave for Unraid?

[dafuzz]

The NIC that is on the motherboard is the default network interface for unraid. 

 installed the quad NIC last night again after removing it some time ago

in the past im quite sure i was able to passthrough all 4 ports 

 

as you can see on the screenshot i posted there is a quad nic there and its allowing me to passthrough 2 of the 4 ports 

 

Some additional info. i had to turn on PCIe ACS override to split them into their own IOMMU groups

Aah, the NICs use the same driver so didn't notice one was the onboard, remove the DHCP configuration from eth1, since it's together with eth2 it might than allow you to pass-through both.

Thanks, i tried what you suggested. Its still greyed out as shown in the screenshot. 

Also rebooted the host 

 

EDIT : Noticed that the devices also had bridging on, i think i was messing with that quite some time ago. Disabled that with the DHCP and now i can pass them through

 

Thank you for the helping hand
