Hyper-V's netvsc driver may register an SR-IOV/VF interface with a mac that matches the synthetic (hv_netvsc) interface. This VF will be enslaved to the synthetic interface, but cloud-init may be racing this process. The [perhaps-yet-to-be-enslaved] VF should never be directly configured, so we filter interfaces that duplicate any hv_netvsc mac address, as this the most reliable indicator that it is meant to be subordinate to the synthetic interface. VF drivers will be mlx4_core, mlx5_core, or mana. However, given that this list of drivers has changed over time and mana's dependency on hv_netvsc is expected to be removed in the future, we no longer rely on these names. Note that this will not affect mlx4/5 instances outside of Hyper-V, as it only affects environments where hv_netvsc is present. c S s& i | ]}|d dkr|d |d �qS )r� � hv_netvscr� r r �r �ir r r rW U s z=filter_hyperv_vf_with_synthetic_interface.<locals>.<dictcomp>c s( g | ]}|d � v r|d dkr|�qS )r� r� rr r rs ��hv_netvsc_mac_to_namer r r X s �z=filter_hyperv_vf_with_synthetic_interface.<locals>.<listcomp>zdIgnoring %r VF interface with driver %r due to synthetic hv_netvsc interface %r with mac address %r.N)r� )rp r� �interfaces_to_remover r r� rz r� r ru r ro A s" � � � �ro c C sP i } t � D ] \}}}}t|d�}|r%|| v r!td|| | |f ��|| |< q| S )zTBuild a dictionary mapping Infiniband interface names to their hardware address.Fz5duplicate mac found! both '%s' and '%s' have mac '%s')r� rD r� )ri r r� ri r r r �get_ib_hwaddrs_by_interfacek s ���rx �url_datac C s� d| vr t �d| � dS | d }z t|�}t|jdk|jdkg�s+t �d|j� W dS W n tyE } z t �d|� W Y d}~dS d}~ww d | vrNd | d < z td i | �� W d S tyb Y dS w ) aD Return true when the instance has access to the provided URL.
