If you are using pci_alias in the flavor that means you are passing through PCI devices. In this case nova does not know (and care) that the PCI device is happen to be an SRIOV VF, or a PFGA or a GPU. Therefore nova will not configure anything SRIOV specific on the passed PCI device.
So I'm setting a bug to Invalid. If you want to use SRIOV VFs as network interfaces in your Nova servers then you have to use Neutron SRIOV support according to https://docs.openstack.org/neutron/pike/admin/config-sriov.html ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1856651 Title: same mac address in SR-IOV VF when doing Passthrough using pci_alias in flavor Status in OpenStack Compute (nova): Invalid Bug description: We are seeing an issue in Openstack pike Devstack where when launching VMs with SR-IOV passthrough using pci_alias in flavor attaching VFs, it is getting the same mac address for each VF. vf 0 MAC 00:00:00:00:00:00, spoof checking on, link-state auto, trust off vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto, trust off vf 2 MAC 66:83:90:5a:78:b3, spoof checking on, link-state auto, trust off vf 3 MAC 66:83:90:5a:78:b3, spoof checking on, link-state auto, trust off Step to reproduce: 1. Configure OpenStack with PCI passthrough capabilities. 2. Create a PCI passthrough flavor with pci_alias property. 3. Deploy VM using flavor in step 2. 4. In compute node check VFs mac address using command "sudo ip link show <Sriov enabled interface name>". Specs: Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 driver: ixgbe version: 4.2.1-k Expected Result: Mac addresses should be unique for VFs Reproducibility- Reproducible/100% To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1856651/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
