Create VM from existing VHD: Preview portal

It can't be done literally in the portal. You will have to use powershell.

1. Create a storageaccount. For example in the portal.

2. Upload the VHD to azure. To do this, run the following line in powershell after logging in with Login-AzureRmAccount (change the parameters between <> and the path to the vhd on your harddisk):

   Add-AzurermVhd -Destination "https://<StorageAccountName>.blob.core.windows.net/<containerName>/<vhdname>.vhd" -LocalFilePath "D:\Virtual Machines\myharddisk.vhd" -ResourceGroupName "<ResourceGroupName" -Overwrite

3. Create an ARM template. Multiple possiblities what you can do. For example choose a template from the Azure Quickstart templates, for example 101

What I have done is:

• Created a new project in Visual Studio 2015.
• Choose the following project: Cloud->Azure Resource Group

• Choose the following template: Windows Virtual Machine

• Changed some parameters and removed all stuff that is not necessary.What it does now is: Create a Windows Virtual Machine using the uploaded vhd as harddisk.It's using a parameters json file now, and also some variables have to be set in the WindowsVirtualMachine.jsonThis could be refactored ofcourse. but for now it will do what's needed.

For this sample you have to have the following directory structure (just like Visual Studio creates it)

ProjectDirectory/Scripts/Deploy-AzureResourceGroup.ps1ProjectDirectory/Templates/WindowsVirtualMachine.jsonProjectDirectory/Templates/WindowsVirtualMachine.parameters.json

4. Execute the powershell scriptOpen up a Powershell command and execute the ps1 script. You only have to pass the location where you want the vm to be created like: (you should already be logged in with Login-AzureRmAccount)

   Before running change the parameters in both json files!
   .\Deploy-AzureResourceGroup.ps1 "West Europe"

The logging should tell you that the VM is created successfully.

Today (Oct 2016) it still can´t be done in the new portal.

But for completeness: You can do it in the old portal (https://manage.windowsazure.com):

Click New - Compute - Virtual Machine - From Gallery.On the left either select MY IMAGES or MY DISKS and select the VHD you want to use.Follow the instructions as usual.
