Correct way of using NIC Virtual Function

[thigobr]

Hi all!

Last year when putting together my home server I tried to use the Mellanox CX3 Virtual Function under Proxmox. I was using the main device as the Proxmox host network interface and tried to assign the VFs to VMs but this would result in the main device losing connection while bringing up/down the VMs...

So my question is: what's the correct way of using VFs? Should I use only the VFs and leave the main device alone? Is there a way to properly use the same card for VMs and the host like I tried before?

I am re-visiting my server configuration and I would like to try VFs again

Did you try using a VF as the Proxmox host network interface and use other VF's in the VM’s?

I did not try yet... But is this the proper setup? I will test soon

Yes I believe it is. It is not possible to both have SR-IOV or direct passthrough on a PCIe device and use that device natively as you found out. It is one or the other.

Is it possible to use SR-IOV VF as the management interface?

Hi everyone, sorry for my English. I spend time to test between ESXi and Proxmox VE and finally find that only PVE allow me to use SR-IOV. As my switch port is not enough, I would like to know if it is possible to use VF as the management interface. I follow this guide...
