PAN-VM OpenStack interface assignments

Hi,

we have come came across the issue that the PAN-VM appliance relies on the PCI topology to assign network interfaces and not the mac address.

This is the a problem, OpenStack the PCI topology is not persistent across reboots (when an instance is recreated, the libvirt config is rebuilt).

It happened to us, that after a reboot the interface assignments were gone.

In OpenStack the metadata feature [2] or the MAC address usually used to assign the correct interfaces [1].

Has anyone come across this or have any idea how to fix it? IMO the PAN-VM should not rely on the PCI topology but rather the mac address (or the metadata service).
