Hyper-V Manager ins Azure Server Management Tools SMT

Manage Hyper-V from Azure Server Management Tools

Microsoft released an updated to the Azure Server Management Tools (SMT) and this improves some of the existing tools such as File Explorer and Device Manager. But the big announcement here is, that you now can manage your Hyper-V Server and Virtual Machines directly from Microsoft Azure from where ever you are. This is one of the great examples of using cloud solutions to extend your on premise environment, By using Management as a Service you basically don’t need to updated anything, you just got this new feature available in the Azure portal and you can start using it.

In this update to the Server Management Tools, Microsoft supports the following VM management functionality:

  • Start/Shutdown/Turn off/Pause/Resume
  • Save State/Delete Saved State
  • Take/Apply & rename checkpoints

You can see the Virtual Machines on which are running on the Hyper-V server

You can also do basic management of checkpoints

Hyper-V Manager Windows 10 Build 14361

Hyper-V Manager just got some new Icons in Windows 10 Build 14361

Microsoft just released a new Windows 10 Insider Preview Build (14361) with a lot of different improvements. The also worked on some changes to the Hyper-V Manager. The Hyper-V Manager finally got some updated Icons. Hyper-V also introduced a new VM Configuration version 8.0 (from 7.1 in the latest Windows 10 and Windows Server 2016 Technical Preview 5 build)

There are also a lot of other improvements espeically to the UI, Windows Ink and they officially introduced Hyper-V Containers on Windows 10.

Introducing Hyper-V Container: You can now use Docker natively on Windows 10 with Hyper-V Containers, to build, ship and run containers utilizing the Windows Server 2016 Technical Preview 5  Nano Server container OS image. A new version of the Docker engine for Windows has also been made available that extends the support of containers while also improving the DockerFile syntax and getting started experience for users. For more details on how to get started with this check out the Windows container documentation or the Windows 10 Getting Started Guide.

 



Hyper-V Gernal Access dinied error

Hyper-V over SMB: Set SMB Constrained Delegation via PowerShell

When you are having configured a Hyper-V over SMB configuration, which means the virtual machines are running on Hyper-V host and are stored on a SMB file share, and you try to manage the virtual machine remotely from Hyper-V Manager or Failover Cluster Manager, you will run into access denied errors. The same error can also happen if you try live migrate the virtual machine. This error is caused because you are using the credentials from the machine which Hyper-V or Failover Cluster Manager is running on to access the file share via the Hyper-V host. This “double-hop” scenario is not by default not allowed because of security reasons. You can find more about Kerberos Authentication on TechNet.

To avoid this error you have to configure the SMB Constrained Delegation in Active Directory to allow this scenario for specific “double-hops”. In Windows Server 2012 Microsoft made setting up Kerberos constrained delegation much easier by introducing resource-based Kerberos Constrained Delegation. This it wasn’t that easy to deploy and required some step. In Windows Server 2012 R2 Microsoft introduced new Windows PowerShell cmdlets to configure SMB Constrained Delegation directly from PowerShell. These cmdlets are offered by the Active Directory PowerShell module.

On your management box or where ever you want to configure SMB Constrained Delegation you have to install the Active Directory PowerShell module. (You don’t need the module on the Hyper-V host or SMB file servers)

Now you can use the following cmdlets.

  • Get-SmbDelegation –SmbServer FileServer
  • Enable-SmbDelegation –SmbServer FileServer –SmbClient HyperVHost
  • Disable-SmbDelegation –SmbServer FileServer [–SmbClient HyperVHost] [-Force]

For example if you are running a two node Hyper-V cluster and you use a Scale-Out File Server cluster (SOFS01) as virtual machine storage, the configuration could look like this.

Because these cmdlets only work with the new resource-based delegation, the Active Directory forest must be in “Windows Server 2012” functional level. A functional level of Windows Server 2012 R2 is not required.

And as I mentioned before you can also use System Center Virtual Machine Manager (VMM) to manage your storage, which uses a different approach and does not need the configuration of Kerberos Constrained Delegation.
