Hi Konrad, Pasi<br><br>Thanks for your inputs. Looks like we(our team) needs to take a step back and evaluate this and other things we have discovered in the past few days. We will get back to you with more questions.<br><br>

&gt; Using PCI passthrough(I believe it is via config file changes) prevents<br>
&gt; other domU&#39;s accessing the NIC correct? If I use it, would the network<br>

</div>If you have two NICs, where one of them is PCI passthrough and<br>
the other dedicated to the guests, then the second can serve as<br>
netback/netfront.<br>
<br>
Thought I wonder if you can have the netback in the guest. This<br>
way you could fiddle with your registers in one domain, and export<br>
a network interface (vif) to the other guests from the domain that<br>
owns the PCI device.<br>
