[Kernel-packages] [Bug 1794477] Re: Accelerated networking (SR-IOV VF) broken in 18.10 daily
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This does look resolved on WS2016 and Azure. However, SR-IOV is broken in another way now on WS2019. Affected proposed kernels: - cosmic proposed - bionic proposed edge - 4.18 based. Tested this with cosmic linux-azure 4.18.0.1006.7 from proposed, same vhd: - SR-IOV with Mellanox CX3 works fine on WS2016, all testing has passed. - SR-IOV with Mellanox CX3/CX4 is broken on WS2019.

[Kernel-packages] [Bug 1794477] Re: Accelerated networking (SR-IOV VF) broken in 18.10 daily
There's a second issue that also affects cosmic/linux-azure: In 4.18, the module pci-hyperv moved from "drivers/pci/host/pci- hyperv.ko" to "./drivers/pci/controller/pci-hyperv.c". That caused the module to be included to the linux-modules-extra instead of the linux- modules package. I'm preparing a fix for it and adding some additional checks to prevent modules to move silently to the linux-modules-extra when its based location has changed. -- 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: Fix Committed Status in linux-azure package in Ubuntu: Confirmed Status in linux source package in Cosmic: Confirmed 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.

[Kernel-packages] [Bug 1794477] Re: Accelerated networking (SR-IOV VF) broken in 18.10 daily
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.
