Best Practices for running Linux on Hyper-V

Sometimes I just need my blog as a reminder or a database to find something in a few months so this is exactly one of this blog posts. Microsoft has a TechNet article where they describe the best practices for Linux VMs running on Hyper-V 2012 or Hyper-V 2012 R2. The article is a list of recommendations for running Linux virtual machine on Hyper-V.

Right now they have 4 recommendations on the list (Source Microsoft TechNet):

  • Use static MAC addresses with failover clustering.
  • Use Hyper-V-specific network adapters, not the legacy network adapter.
  • Use I/O scheduler NOOP for better disk I/O performance.
  • Add “numa=off” if the Linux virtual machine has more than 7 virtual processors or more than 30 GB RAM.

SCVMM Bare-Metal Fails

Add drivers to SCVMM Bare-Metal WinPE Image

A long time ago I wrote a blog post on how you can use System Center Virtual Machine Manager Bare-Metal Deployment to deploy new Hyper-V hosts. Normally this works fine but if you have newer hardware, your Windows Server Image does may not include the network adapter drivers. Now this isn’t a huge problem since you can mount and insert the drivers in the VHD or VHDX file for the Windows Server Hyper-V image. But if you forget to update the WinPE file from Virtual Machine Manager your deployment will fails, since the WinPE image has not network drivers included it won’t able to connect to the VMM Library or any other server.

You will end up in the following error and your deployment will timeout on the following screen:

“Synchronizing Time with Server”

SCVMM Bare-Metal Fails

If you check the IP configuration with ipconfig you will see that there are no network adapters available. This means you have to update your SCVMM WinPE image.

First of all you have to copy the SCVMM WinPE image. You can find this wim file on your WDS (Windows Deployment) PXE Server in the following location E:\RemoteInstall\DCMgr\Boot\WIndows\Images (Probably your setup has another drive letter.

WDS SCVMM Boot WIM

I copied this file to the C:\temp folder on my System Center Virtual Machine Manager server. I also copied the extracted drivers to the C:\Drivers folder.

After you have done this, you can use Greg Casanza’s (Microsoft) SCVMM Windows PE driver injection script, which will add the drivers to the WinPE Image (Boot.wim) and will publish this new boot.wim to all your WDS servers. I also rewrote the script I got from using drivers in the VMM Library to use drivers from a folder.

Update SCVMM WinPE

This will add the drivers to the Boot.wim file and publish it to the WDS servers.

Update WDS Server

After this is done the Boot.wim will work with your new drivers.

Hyper-V Share

Hyper-V is eating VMware’s lunch

During the WPC 2014 Keynote Microsoft COO Kevin Turner showed the following slide and commented it:

Hyper-V is eating VMware’s lunch

 

Hyper-V has now 30,6% market share in x86 Server Virtualization which means Microsoft won 4.6% since the release of Windows Server 2012. VMware is now at 46.4% market share which means they lost 5.1% market share since the release of Windows Server 2012 Hyper-V.

And this because of good reasons, like great features and 4 times lower cost than VMware. So if you are still running VMware you should definitely have a look at Hyper-V now!



Distinguished Judges for the UCS Power Scripting Contest

Cisco UCS PowerShell Scripting Contest

In the Microsoft world PowerShell is the tool to automate everything especially in your datacenter. I already mentioned that Cisco offers some great enhancements for the Microsoft Datacenter stack. If you are using a Cisco UCS solution you can integrate System Center Virtual Machine Manager, Orchestrator and others. But Cisco does also offer a PowerShell module for the UCS called Cisco UCS PowerTool. The UCS PowerTool allows you to automate management and deployment tasks very easily via Windows PowerShell. By the way, one of the coolest features in the Cisco UCS PowerTool is the ConvertTo-UCScmdlet.

Cisco announced the UCS Power Scripting Contest

Everyone is invited to share their scripts and possibly win some prizes by entering the UCS Power Scripting Contest on the Cisco Communities.  The contest will run until May 11th.  A distinguished panel of judges (Jeffery Snover, Rob Willis, Don Jones, Hal Rottenberg and Thomas Maurer) along with other members of the community will select the grand prize winner from a set of five finalists.

Distinguished Judges for the UCS Power Scripting Contest

I am proud to be one of the Distinguished Judges for the UCS Power Scripting Contest and I hope we will see some great solutions. To get more information about the contest check out the Cisco Blog from Bill Shields and the UCS Power Scripting Contest website.

Save PowerShell Object to file for Remote Troubleshooting

This is not something new to the most of you PowerShell guys out there, but still there are a lot of IT Pros which do not know about this. Sometimes we have to do some remote troubleshooting without having access to the system itself. The thing you can do is to let the customer send you some screenshots but that doesn’t really show everything and maybe you have to contact the customer like 100 times to get the right information. A better solution is to let the customer to run a PowerShell command or script and send you the output. But even a text file or screenshot of the PowerShell output is not the best solution. If you get a lot of text in a TXT file it is hard to sort it and maybe there are some information missing because the txt output does not include all information of the PowerShell object.

I have started to use a simple method to export PowerShell objects to a XML file and import the object on another system. This can be done by the PowerShell cmdlets Export-Clixml and Import-Clixml.

What I do is, I tell the customer to run the following command to generate a XML with the PowerShell objects about his disks for example.

After I got this XML file, I can import it here on my local system and can work with it as I would be in front of the customer system.

CLIXML Export Import

As I said, this is nothing new but this can save you and your customer some time. Of course this works with other objects not just disks ;-) For example you can get Cluster Configurations, Hyper-V Virtual Switch Configurations and much more.
