Migrate On-Premises VHD files to Azure

You may need to move a couple of Azure Virtual Machines from on-premises to your Azure subscription. Thanks to Windows PowerShell, uploading a VM to Azure is really easy to do! You must check only one prerequisite before uploading your VM to Azure: you will need to check what type of virtual hard disk is being used by the virtual machine. Hyper-V can use either VHD or VHDX based virtual hard disks. However, only VHD disks can be uploaded to Azure. Azure does not support VHDX disks.

Choosing proper V2V converter for smooth VM migration

Migrating your VMs from one hypervisor to another may be a bit of a challenge if you don’t have some decent virtual machine converter at hand. Different hypervisors have their own proprietary VM formats: VMDK, VHD and VHDX, QCOW, you name it. The problem is that one VM format can be not supported on other platforms. In this case, a V2V converter is a must-have. Now, the question arises: which converter should I choose?

Windows Server 2016 Nano Server – Installation and Management

Time to continue our conversation about that “scaled down even further” Server 2016 installation option. In my previous article, I covered general concepts around Nano Server, now I want to switch gears and talk about more practical aspects: installation and management. At the end of the day, you would agree that the best way to learn new technology it is trying to use it – this way you will be exposed to its strengths and weaknesses directly, and can get the real understanding of whether it works for you or not. Though at this point even Microsoft admits that despite all its greatness, at the moment, Nano Server has quite limited utility as it supports only a small subset of roles and features out of those which you can find in full GUI version of Windows Server.

Nano Server Image Builder tool

In this topic, I’ll show you how to prepare a Nano Server image which will be deployed in a virtual machine. The operating system will be configured to run containers. To create the Nano Server image, I’ll use the Nano Server Image Builder tool which is a graphical interface to prepare the image in VHD, VHDX or WIM file format.

Shared virtual hard disks in Hyper-V 2016


A new feature called VHD Set for Hyper-V in Windows Server 2016 has been introduced by Microsoft. It allows sharing virtual hard disks between several servers in order to implement guest cluster easily without using complex technologies such as NPIV, virtual HBA, or virtual SAN.

As VHD Set, Shared VHDX enables sharing a virtual hard disk between multiple virtual machines. This feature is useful for implementing a guest cluster where shared disks are required (e.g., SQL Server AlwaysOn/FCI or File Servers).

Deploy an Azure VM from a generalized image in Azure RM portal

Microsoft Azure provides a way to deploy Azure VM from the Marketplace or from a generalized image. When you deploy the Azure VM from the Marketplace, no customization is deployed. You have to configure the operating system as your master. When you have several Azure VMs to deploy, the customization of each system can be time consuming. A lot of companies have a master or a baseline image in a VMDK for VMWare, in a VHD(X) for Hyper-V or in a WIM image. In this topic we will see how to create a generalized image from a single Azure VM and how to deploy Azure VM from this generalized image.

In the old portal (, all steps can be done from the GUI but also by using PowerShell. In the new portal (, you have to use PowerShell because it is not yet integrated to the portal. In this topic, I will work from the new portal (AzureRM).
