the problem is that when using virtual adapters you in essence use a switch and thus we cannot implement the bump in the wire as the collision domain will prevent it from working, So yes, you need PCIe passthrough

Hi Luca,

Thanks for getting back!

My knowledge of some of this is a little lacking, so forgive me if this is
naive.

However - what if you created a dedicated bridge interface in KVM, attach a
single physical Ethernet interface to that bridge, and only assign that
bridge to the ntopng Edge VM?

(I'm sorry, I didn't understand what you meant by bump in the wire).

Thanks!
Victor
