Canonical & Microsoft make Azure-tailored Linux kernel

Canonical has announced that it is joining forces with the Microsoft Azure team to build an Azure-tailored Linux kernel for Ubuntu Cloud Images of Ubuntu 16.04 LTS. The new kernel will receive the same level of support and security maintenance offered to supported kernels but is not yet compatible with the Canonical Livepatch Service – if this doesn't matter to you, then you’ll be able to enjoy the improvements the kernel brings.

The kernel is provided by the linux-azure kernel package, here are the highlights from Canonical:

  • Infiniband and RDMA capability for Azure HPC to deliver optimised performance of compute intensive workloads on Azure A8, A9, H-series, and NC24r.
  • Full support for Accelerated Networking in Azure. Direct access to the PCI device provides gains in overall network performance offering the highest throughput and lowest latency for guests in Azure. Transparent SR-IOV eliminates configuration steps for bonding network devices. SR-IOV for Linux in Azure is in preview but will become generally available later this year.
  • NAPI and Receive Segment Coalescing for 10% greater throughput on guests not using SR-IOV.
  • 18% reduction in kernel size.
  • Hyper-V socket capability – a socket-based host/guest communication method that does not require a network.
  • The very latest Hyper-V device drivers and feature support available.
