Ubuntu on Microsoft Azure

Microsoft and Canonical create Azure optimized Ubuntu Kernel

Ubuntu is a popular choice for Virtual Machines running on Microsoft Azure and Hyper-V. Yesterday Microsoft and Canonical that they will provide an Azure Tailored Kernel for Ubuntu. Microsoft and Canonical were already working on a lot of projects together, like Linux Containers on Windows using Docker, or the Windows Subsystem for Linux.

Canonical, with the team at Microsoft Azure, are now delighted to announce that as of September 21, 2017, Ubuntu Cloud Images for Ubuntu 16.04 LTS on Azure have been enabled with a new Azure tailored Ubuntu kernel by default.  The Azure tailored Ubuntu kernel will receive the same level of support and security maintenance as all supported Ubuntu kernels for the duration of the Ubuntu 16.04 LTS support life.

The kernel itself is provided by the linux-azure kernel package. Some of the special feature this kernel provides are:

  • Infiniband and RDMAcapability for Azure HPC to deliver optimized 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.
  • 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.

I am sure these improvements will not only help Ubuntu Virtual Machines running on Azure, but also Ubuntu Virtual Machines running on Hyper-V

Canonical and Microsoft also promise to work close in the future to deliver more new feature.

As we continue to collaborate closely with various Microsoft teams on public cloud, private cloud, containers and services, you can expect further boosts in performance, simplification of operations at scale, and enablement of new innovations and technologies.

Really looking forward how this works. Also funny to see the comments on the Tweet from the @Ubuntu on twitter, which shows how many people live in the old world.



Linux on Windows 10

Crazy times – You can now run Linux on Windows 10 from the Windows Store

In the past weeks, some crazy things are happening. Think you’re way back in the time of 2003, could you have ever imagined that Microsoft offers you to run Linux on Windows 10? Well, this is exactly what is happening in the past months.

With one of the Windows 10 releases, Microsoft added the Windows Subsystem for Linux, which allowed you to run a Ubuntu version on your Windows 10 devices. In the past few days and weeks, Microsoft now announced that you can now download and install SUSE Enterprise Server, openSUSE Leap and Ubuntu (my guess there will be more to come) from the Windows Store. All you need today is the latest Windows Insider Build 16237 (it also works with a couple of older insider builds), and you will be able to install these versions. For the mainstream, this will be available in the Windows 10 Fall Creators Update arriving in the Fall of 2017. The Windows Subsystem for Linux will also be part in the next Windows Server RS3 release.

Ubuntu Windows 10 Store

If you want to know more about how it works check out Scott Hanselman blog about Ubuntu now in the Windows Store: Updates to Linux on Windows 10 and Important Tips

One great thing, Scott describes in his blog if you want to configure the different Windows Subsystems for Linux and for example, set the default one, you can use the command line with the wslconfig utility.

WSLConfig on Windows 10

wslconfig #Set default distribution to Ubuntu wslconfig /s Ubuntu

At the Microsoft Build conference 2019, Microsoft also showed the latest Windows Subsystem for Linux 2 (WSL 2). If you have any questions, let me know in the comments.



Bash on Windows 10

How to Install Linux Bash on Windows 10

With the Windows 10 Anniversary Update, which was released by Microsoft in Summer 2016, Microsoft included a Windows Subsystem for Linux in Windows 10. This allows you to enable Linux Bash on Windows 10. In this blog post I quickly want to show how you can enable the Windows Subsystem for Linux on Windows 10. This is great if you want to use some Linux tools on your Windows 10 machine. I use it for example to use SSH to connect to Linux Virtual Machines on Azure.

First you have the following requirements:

  • Windows 10 Anniversary Update – Windows 10 Build 14393 and higher
  • 64-bit versions of Windows 10
  • Internet Connection to download the Windows Subsystem for Linux in Windows
  • Active Developer Mode in Windows 10

First enable Developer Mode There are two option you can do this

Open the Settings App, go to Update & Security, go to For developers and enable Developer mode:

Windows 10 - Developer Mode

You can also use the following PowerShell command to enable Developer Mode:

 
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock" /t REG_DWORD /f /v "AllowDevelopmentWithoutDevLicense" /d "1"

After this you can enable the Windows Subsystem for Linux as a Windows Feature in the Control Panel or PowerShell

Windows 10 - Windows Subsystem for Linux

Run the following PowerShell command to enable the Windows Subsystem for Linux:

Enable Windows Subsystem for Linux using PowerShell

 
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

After that you will need to restart your computer.

Now you can open up PowerShell or the command prompt and start using bash. (You can also start Bash directly from the Start Menu)

Bash on Windows 10

Hope this helps you to get started.

 



Install Ubuntu 12.04 on Hyper-V

Some months ago I made a blog entry about “Install CentOS on Windows 8 Hyper-V“. Now with the new Linux kernel 3.0 the Hyper-V Integration Components are integrated in the kernel. Now Ubuntu 12.04 will be based on the new Linux kernel and this is why it should run perfectly on Microsoft Hyper-V.

  1. Download Ubuntu on Ubuntu.com. Until 12.04 is released you can download the daily builds from here.
  2. Start the Hyper-V Manager and create a new Virtual Machine
  3. Install Ubuntu 12.04
    Hyper-V Ubuntu 12.04
  4. after the Installation everything should work fine :)
    Hyper-V Ubuntu 12.04
