Are you using built in nics on your hypervisor? If so, then pci passthrough will likely pass both as they as possibly on the same pci device. At least that is how my dells work. Honestly you should just be able to put nic two on its own network untagged and then assign that network to the hypervisor with the connection. Without SR-IOV support those nics will be dedicated to that VM. 

Just depends on your use case. What is the big picture?

Yes, enabled io-mmu.   I'm not sure if what I'm doing is right though.  So if there is a better way of accomplishing what I'm trying to do, send me to some reading material so I dont take up too much of everyone's time.  I'll read up on it.  If its a simple do-this-and-that, then I'll try it.

Thanks!

Looks like you are trying to use SR-IOV. Did you enable iommu on the hypervisors? Do your hypervisors support SR-IOV.

Need some guidance on this one.

Config:
1U with 2 NICs.
NIC 1 plugged to local switch - gets local IP
NIC 2 plugged direct to cable modem - need to set IP inside VM to public static IP
VM will be CentOS, already know how to configure NIC once I can get the 2nd NIC assigned to it.

Do I use PCI passthru?  Or where do I start to get this configured?  I did setup NIC 2 under Network --> Networks.   Created a NIC called "external_NIC".  External NIC has description and then I configured 2 DNS servers which are given to me by the ISP.

Under Compute --> Hosts --> <My Host> --> Network Interfaces (I have both NICs showing as up) --> Setup Host Networks ---> NIC 2 is the interface --> Assignment of Logical networks is "external_NIC".

I was assuming I was done, so I go to my VM add NIC 2, click run and I see:

Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:
  • The host <MY HOST> did not satisfy internal filter Network because there are no free virtual functions which are suitable for virtual nic(s) nic2. A virtual function is considered as suitable if the VF's configuration of its physical function contains the virtual nic's network/network label.
Need guidance on what to read to get this working.

Thanks!
