This article covers the older managed image technology. For the most current technology, customers are encouraged to use [Azure Compute Gallery](azure-compute-gallery.md). All new features, like ARM64, Trusted Launch, and Confidential VM are only supported through Azure Compute Gallery. If you have an existing managed image, you can use it as a source and create an Azure Compute Gallery image. For more information, see [Create an image definition and image version](image-version.md).

One managed image supports up to 20 simultaneous deployments. Attempting to create more than 20 VMs concurrently, from the same managed image, may result in provisioning timeouts due to the storage performance limitations of a single VHD. To create more than 20 VMs concurrently, use an [Azure Compute Gallery](shared-image-galleries.md) (formerly known as Shared Image Gallery) image configured with 1 replica for every 20 concurrent VM deployments.

To create a managed image from a VM that doesn't use managed disks, you need the URI of the OS VHD in the storage account, in the following format: https://*mystorageaccount*.blob.core.windows.net/*vhdcontainer*/*vhdfilename.vhd*. In this example, the VHD is in *mystorageaccount*, in a container named *vhdcontainer*, and the VHD filename is *vhdfilename.vhd*.

```azurecli

## CLI: Create a VM in another resource group

+

You can create VMs from an image in any resource group within your subscription. To create a VM in a different resource group than the image, specify the full resource ID to your image. Use [az image list](/cli/azure/image#az-image-list) to view a list of images. The output is similar to the following example.
The following example uses [az vm create](/cli/azure/vm#az-vm-create) to create a VM in a resource group other than the source image, by specifying the image resource ID.
One managed image supports up to 20 simultaneous deployments. Attempting to create more than 20 VMs concurrently, from the same managed image, may result in provisioning timeouts due to the storage performance limitations of a single VHD. To create more than 20 VMs concurrently, use an [Azure Compute Gallery](shared-image-galleries.md) (formerly known as Shared Image Gallery) image configured with 1 replica for every 20 concurrent VM deployments.
