SR-IOV and IOMMU

[spetrillo]

Hello all,

I have enabled SR-IOV on two of four network ports. I am not seeing them listed in my IOMMU list, although I see them showing up in the Network dialog of my PVE server. Whats going on here? Anyone know? Do I need to enable it on all four ports?

Thanks,
Steve

if you wanna see anything different in your IOMMU Group, you need to enderstand that a real physical card ( don't care about number of ports) can only be saw in 1 IOMMu group.

Did you have activated this feature on the same physical adapter?

Another think:
if you want to passthrough the physical card, you need to destroy ALL entry of them in your network/interfaces list too. Destroy too " inet manual' entry.

Retry checking yours iommu segmentation after, you will don't have problem (i wish for ^^)

If I remove all the physical interfaces from the /etc/network/interfaces file how will PVE know about them then? Are you just saying that the iface statements need to be removed and the auto statements stay?
