Haven't reproduced this at all, but based on just thinking about this and looking at the sosreports, I think this is a real bug. I believe when we generate the metadata, we match the libvirt NIC (which has information like the MAC and PCI addresses) with its corresponding VirtualInterface nova object (which has information like the device tag) on MAC address, which is the only piece of unique information that both data structures share. However, PF devices will appear in the libvirt XML as <hostdev> and not <interface>, and more importantly they appear *without* their MAC address: <hostdev mode="subsystem" type="pci" managed="yes"> <source> <address bus="0x06" domain="0x0000" function="0x1" slot="0x00"/> </source> </hostdev> Compared to the VIF JSON, in which the MAC appears: { "address": "a0:36:9f:ba:04:1e", [...] "profile": { "pci_slot": "0000:06:00.1", "pci_vendor_info": "8086:1528", "physical_network": "sriov" }, [...] } I have no ideas as to the fix for now, nor whether it will be backportable to OSP10, given that Newton has been EOLed upstream.
Hey Ricardo, While my patch is waiting for upstream reviews, I've made an OSP10 scratch build [1]. If you want you can play around with it in a test env, to confirm whether it actually fixes the bug or not. I want to be absolutely clear that the build was done with code that is merged absolutely nowhere, and thus comes with no promises whatsoever, except that I did my best to fix the bug. Cheers!
