Create a VM from a managed image
You can create multiple VMs from a managed VM image using PowerShell or the Azure portal. A managed VM image contains the information necessary to create a VM, including the OS and data disks. The VHDs that make up the image, including both the OS disks and any data disks, are stored as managed disks.
You need to have already created a managed VM image to use for creating the new VM.
Use the portal
- Open the Azure portal.
- In the left menu, select All resources. You can sort the resources by Type to easily find your images.
- Select the image you want to use from the list. The image Overview page opens.
- Click + Create VM from the menu.
- Enter the virtual machine information. The user name and password entered here is used to log in to the virtual machine. When complete, click OK. You can create the new VM in an existing Resrouce Group, or choose Create new to create a new resource group to store the VM.
- Select a size for the VM. To see more sizes, select View all or change the Supported disk type filter.
- Under Settings, make changes as necessary and click OK.
- On the summary page, you should see your image name listed for Private image. Click Ok to start the virtual machine deployment.
You can use PowerShell to create a VM from an image using the simplified parameter set for the New-AzureRmVm cmdlet. The image needs to be in the same resource group where you want to create the VM.
This example requires the AzureRM module version 5.6.0 or later. Run
Get-Module -ListAvailable AzureRM to find the version. If you need to upgrade, see Install Azure PowerShell module.
The simplified parameter set for New-AzureRmVm only requires that you provide a name, resource group and image name to create a VM from an image, but it will use the value of the -Name parameter as the name of all of the resources that it creates automatically. In this example, we provide more detailed names for each of the resource, but let the cmdlet create them automatically. You can also create resources, like the virtual network, ahead of time and pass the name into the cmdlet. It will use the existing resources if it can find them by their name.
The following example creates a VM named myVMFromImage, in the myResourceGroup resource group, from the image named myImage.
New-AzureRmVm ` -ResourceGroupName "myResourceGroup" ` -Name "myVMfromImage" ` -ImageName "myImage" ` -Location "East US" ` -VirtualNetworkName "myImageVnet" ` -SubnetName "myImageSubnet" ` -SecurityGroupName "myImageNSG" ` -PublicIpAddressName "myImagePIP" ` -OpenPorts 3389
