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!

Updates and Recommendations not working in SCOM 2016

Not so long ago, there was a thread about this issue on TechNet Forums – long story short, in some cases (if you didn’t do a clean installation of System Center 2016 – Operations Manager, for example), the shiny, new feature called Updates and Recommendations didn’t work.

Even better – there was a rather cryptic error saying “An error occurred while displaying the Updates and Recommendations view. This might be because the database query has encountered an error…”.

image

So… it looks that maybe the database query has indeed “encountered an error”.

What can we do to make sure and resolve this?

As the user Chandra Bose suggested, we can look for duplicates in our imported management packs… and maybe we will be smarter then.

PowerShell command we can use:

This will list our imported management packs and their versions, and we can start looking for duplicate(s).

image

In my case, there were some – some of them were the two management packs called Microsoft.SystemCenter.WebApplicationSolutions.Library.Resources.*.

To get a better look on those two, we can use the following command:

And the output looks like this:

image

image

This shows that we really have two “duplicate” management packs in our SCOM database, one installed in 2013, and another in 2014 (why? and how? don’t really matter Smile). We need to remove one, obviously.

For that, we can use the following command (by using the Id property from previous command):

And, if there are no more duplicates, our Updates and Recommendations view should work now:

Hope this helps.

Cheers!

Advanced Technology Days 12

Another Advanced Technology Days are now behind us.

It was a great conference, with so many familiar faces (and so many new ones). I didn’t like this year’s venue as much as the last one (let’s be honest – nothing beats a movie theater! Smile), but it was fine – it’s always about the great people, not the venue itself.

This year I was speaking about the new System Center 2016 suite and, judging by the full room (thank you!), this topic is very hot right now. I really like the new features in Virtual Machine Manager and the new “speedy” Operations Manager (with web portal which finally works in “modern” browsers Smile).

Slides (which are actually customized Microsoft Ignite slides – thank you), are uploaded to my SlideShare.

And now… looking forward to Advanced Technology Days 13. Smile

Cheers!

P.S. Thanks for the pics – Goran & Igor!

Advanced Technology Days (ATD) 10 – recap

Another great conference is behind us – Advanced Technology Days 10 (or just ATD 10). Two-day conference, Wednesday and Thursday, about the latest and greatest from Microsoft, just in time for some of the important announcements, and with more than a glimpse into the future of technology – pretty cool. Smile

I’ve had two sessions – on Wednesday, I’ve had a session called Što nam donosi Windows Server vNext (Technical Preview)? (or “What’s new in Windows Server vNext (Technical Preview)?”), where I’ve outlined the major news in this prerelease version of the next Windows Server. There really is a lot to talk about, as Windows Server vNext brings so many news, even in this, somewhat early, stage in development cycle.

The session that I’ve had on Thursday was called Što nam donosi System Center vNext (Technical Preview)? (or “What’s new in System Center vNext (Technical Preview)?”), and there I’ve shown what is there in Technical Preview today with the preview of the new Microsoft Azure Operational Insights, which also entered the “public preview” phase during the conference. You can sign up and try it at https://opinsights.azure.com/.

Overall experience was great – once again located in a movie theatre, with lots of great people, networking, combined with a flawless demo experience (plug ’n’ play) and great timing... actually, I can’t wait for Advanced Technology Days vNext! Smile

I’m so happy that I was invited to speak (big thanks to all involved!), and got the opportunity to participate with my view on all the great stuff included in those releases of very important products.

More info is available at http://atd.mscommunity.hr/ and https://www.facebook.com/MicrosoftATD.

Hosts have “Needs Attention” status after installing the VMM 2012 R2 UR4

For those who installed the Update Rollup 4 for System Center 2012 R2 Virtual Machine Manager, you may be facing this somewhat “strange issue” right after the installation – your hosts will have the “Needs Attention” status.

image

And now the “strange” part – if you open the host Properties window, and check the Status tab, you’ll may see that everything is green.

image

So, what needs the attention then?
The answer is – VMM agent needs the attention, and that’s the cause of this “issue” (you’ll need to run Update Agent action on affected hosts).

image

And, finally, status of your hosts should be OK again.

image

Hope this helps!

P.S. Read the KB document thoroughly – there is a part which mentions the manual update of System Center Virtual Machine Manager DHCP Server (x64) component. It should be like this:

Microsoft System Center Configuration Manager: High availability and performance tuning

Not so long ago, I've got yet another book from Packt Publishing – "Microsoft System Center Configuration Manager: High availability and performance tuning", written by a fellow MVP, Marius Sandbu.

As someone who is not an Configuration Manager expert, I've really enjoyed reading this book.

Why? Because it provides great reference list of all the things that make Configuration Manager deployment highly available (from Active Directory and SQL to the Configuration Manager components), packed in a great format (not too long, about 150 pages), and well-written. It also provides, from my perspective, high-level steps that can be taken to fine-tune your deployment – an aspect of the deployment which is usually forgotten.

I would recommend this book to anyone that needs to learn about the principles of high availability and performance tuning of Configuration Manager – it's not a long read, it will save you some time and certainly help you get started right away! However, if you need deep-down information about specific component, in a "Bible" format, you'll need to grab at least one additional book…

You can order this book here.
