Hi,

Can i use PCI-Passthru and SRIOV on the same hosts for different ports? ens1f0-1 SRIOV with multiple VFs and ens2f0-1 pci-passthru ?

I have 2 apps on the same hosts one supports SRIOV and the other one only supports pci-passthru.

thanks,

Correction: Cannot create a VM with 1-port VF and another PF. So same host can have PF and VF but same VM?

Hi Demirel,

 

 

If you have two network controller, each should be function separately without dependency, in case there is restriction please check on the host level, you can double chck with Redhat* support for similar implementation.

 

 

Can you share more specific information regarding the application

 

you use for passthrough and the application for SR-IOV.

 

 

Please elaborate also regarding "Cannot create a VM with 1-port VF and another PF. So same host can have PF and VF but same VM"

 

 

What is the application used for creating VM? What is the error message?

 

 

 

Thanks,

Hi,

Double checked this with RH, it is possible. We were using a an application from Sandvine for traffic steering. It was a misconfig
