commit efc27ff84c3f38fbcbf75b0dc230963c58d093e4 Author: Sean Mooney <[email protected]> Date: Fri Jul 3 15:58:02 2020 +0000 Lookup nic feature by PCI address In some environments the libvirt nodedev list can become out of sync with the current MAC address assigned to a netdev, As a result the nodedev lookup can fail. This results in an uncaught libvirt exception which breaks the update_available_resource function resultingin an incorrect resource view in the database. e.g. libvirt.libvirtError: Node device not found: no node device with matching name 'net_enp7s0f3v1_ea_60_77_1f_21_50' This change removes the dependency on the nodedev name when looking up nic feature flags.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1883671 Title: [SRIOV] When a VF is bound to a VM, Nova can't retrieve the PCI info Status in OpenStack Compute (nova): Fix Released Bug description: Nova periodically updates the available resources per hypervisor [1]. That implies the reporting of the PCI devices [2]->[3]. In [4], a new feature was introduced to read from libvirt the NIC capabilities (gso, tso, tx, etc.). But when the NIC interface is bound to the VM and the MAC address is not the one assigned by the driver (Nova changes the MAC address according to the info provided by Neutron), libvirt fails reading the non-existing device: http://paste.openstack.org/show/794799/. This command should be avoided or at least, if the executing fails, the exception could be hidden.
