Fix VF-rep lookup routine to use parent PF number The current logic in get_representor_port() matches the VF number with the one in 'phys_port_name' file. If and when multiple PFs on the same card are configured in switchdev mode, we could end up returning a wrong representor device. Fix this by including the parent PF number also in this logic, when 'pfXvfY' (or vfY@pfX) format is used in 'phys_port_name' file. github: https://github.com/openstack/os-vif/commit/84688a22db22039f5566c1439c3983db23672a45 This patch appear to be missing from nova-compute container.
This was first resolved in python-os-vif-1.9.0-1.el7, which is included in the oldest version of nova-compute container I can see, 14.0-94 [1]. You haven't provided package versions but I suspect you simply need to update to a newer release that included that python-os-vif package version.
