Hi all, I have been having an issue for over a year with several Xen installations and have not been able to find out if this is just something I am missing. Basically I am trying to configure a firewall with two ethernet cards in a domU using pci passthrough. I am hiding the Ethernet cards at boot time via the pciback.hide kernel option. Right now I am running Xen 3.3.0 and the two Ethernet
