No VF shows up inside the VM and lspci didn’t show any Mellanox drivers in use. We tested the daily build on Hyper-V also, but there the Mellanox VF is functional, with the same mlx4 drivers. To give more details about this: • No mellanox logs are showing up in dmesg or syslog. • Modinfo mlx4_core/mlx4_en finds the module, but lsmod doesn’t show it as loaded, although Accelerated Networking is enabled for the Azure VM, so this should happen transparently. • Modprobe -r mlx4_core && modprobe mlx4_core is giving 0 exit code, but nothing really happens. And no Mellanox messages are logged in dmesg/syslog. - There are no entries in the logs to show anything about the drivers or netvsc/pci-hyperv that might relate to this issue.
