Creating some virtual machines in Azure with PowerShell

The other day I was creating some Linux virtual machines (I know, I know...) and, with Azure being my preferred hosting platform, I've decided to create this machines by using a simple PowerShell script. Not because I'm so good at PowerShell, but because I like it... and sometimes I really don't like clicking through the wizard to create multiple machines.

I wanted to create multiple machines with ease, each with "static" IP address from the provided subnet, accessible via the Internet (SSH, HTTP) and running the latest Ubuntu Linux, of course.

So, I was browsing through the official documentation (a.k.a. docs.com, more specifically https://docs.microsoft.com/en-us/azure/virtual-machines/linux/quick-create-powershell), and I've come up with this (my version of the official docs):

If this helps you with similar task - you're welcome.

Cheers!

Deploying Linux machines by using System Center 2016: Virtual Machine Manager templates

In light of "Microsoft loves Linux" initiative, you can now deploy your Linux virtual machines by using templates in the System Center 2016: Virtual Machine Manager. As I was searching on how to do this (successfully), there were couple of articles that helped, so I’ve decided to do a short list of all the necessary steps (in one place).

Steps to make your Linux VM template deployments work:

  • create a new (Generation 2) virtual machine (as you would normally do)
  • install the Linux operating system in that virtual machine (as you would normally do)
    • HINT: A list of supported Linux distributions and versions on Hyper-V is available here.
  • install the Linux Integration Services (LIS) (as per this post):
    • open the "modules" file
    • add the following to the end of this file:
    • save it (Ctrl+X and Y)
    • install LIS and reboot the machine by using the following commands:
    • check if the services are running by using the command:
  • install the Virtual Machine Manager agent (as per this post):
    • share the folder C:\Program Files\Microsoft System Center 2016\Agents\Linux on your VMM machine
    • copy the VMM agent files to Linux virtual machine
      • as a real Windows admin, I did it through the GUI
    • install the agent:
  • fix the boot for Generation 2 virtual machine (boot information is by default stored in the VM configuration file, not on disk – Ben wrote a great article on this “issue”)
    • Ben’s way (didn’t work for me):
      • change directory to the boot EFI directory
      • copy the ubuntu directory in to a new directory named boot
      • change directory to the newly created boot directory
      • rename the shimx64.efi file
    • TriJetScud’s way in the comments (worked for me with Ubuntu 16.04 Generation 2 VM):
  • shutdown the virtual machine and copy its VHDX to the VMM Library
    • HINT: Don't forget to refresh the VMM Library.
  • go to the VMM Library, right-click the copied VHDX and select the Create VM template option
  • proceed with creating the template as you normally would, to the part Configure Operating System
    • HINT: If you are using Secure boot, don’t forget to select the MicrosoftUEFICertificateAuthority template in hardware settings.
  • there, under Guest OS profile, you select the option to create a new Linux operating system customization settings
  • next you specify your guest OS settings and finish creating the template
  • now you can create a new Linux virtual machine from the template you’ve configured!

Hope it helps!

Cheers!
