We already have identified the problem with bionic/azure-edge 4.18.0-1004. There was an issue on this version packaging that caused most of the modules to be included to the linux-modules-extra package instead of the linux-modules package.
The azure kernels do not install the linux-modules-extra package by default, and that's the reason the Mellanox driver wasn't found. As an workaround for 4.18.0-1004 the extra package can be installed with the command "apt-get install linux-modules-extra-azure-edge". The version for the current cycle (4.18.0-1005) is already fixed and should be built in our PPA soon. We will post an update when this version is already available on the PPA. The corresponding cosmic/azure was not affected. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-azure in Ubuntu. https://bugs.launchpad.net/bugs/1794477 Title: Accelerated networking (SR-IOV VF) broken in 18.10 daily Status in linux package in Ubuntu: In Progress Status in linux-azure package in Ubuntu: Confirmed Status in linux source package in Cosmic: In Progress Bug description: While testing Ubuntu 18.10 daily from cloud-images repo, on Azure, we discovered that accelerated networking wasn’t working inside the VM. 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.
