Switch from linux-virtual to linux-azure for Accelerated Networking support

vegan_vicky

We have Azure VMs running Ubuntu 16.04.3 LTS that we would like to use the Azure Accelerated Networking feature on. The minimum kernel version needed is 4.11.0-1013, but currently with apt-get upgrade we can only get to 4.4.0-109-generic. Also apt list --installed linux* shows we are using the linux-virtual kernel package instead of the linux-azure kernel package. Should we switch to the linux-azure kernel package and if so what are the steps...

Great question — answering as the UphillTech team:

The following worked to switch from the linux-virtual package to the linux-azure package: sudo apt install linux-azure sudo apt purge linux-virtual sudo apt autoremove sudo reboot After a reboot we now see the updated kernel and stats for the Mellanox VF device: uname -a Linux MyVM 4.13.0-1005-azure #7-Ubuntu SMP Mon Jan 8 21:37:36 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux ethtool -S eth0 | grep vf_ vf_rx_packets: 510 vf_rx_bytes: 721043 vf_tx_packets: 892 vf_tx_bytes: 200765 vf_tx_dropped: 0
