DEMO Create a Managed Image of a Generalized VM in Azure - SYSPREP

create a managed image of a generalized VM in azure
A managed image resource can be created from a generalized virtual machine (VM) that is stored as either a managed disk or an unmanaged disk in a storage account. The image can then be used to create multiple VMs.
Generalize the Windows VM using Sysprep
Sysprep removes all your personal account and security information and then prepares the machine to be used as an image.
This lecture explains how to capture an existing Virtual Machine and build a new VM out of it.
Clone a managed image to a Shared Image Gallery image
If you have an existing managed image that you would like to clone and move into a Shared Image Gallery, you can create a Shared Image Gallery image directly from the managed image. Once you have tested your new image, you can delete the source managed image. You can also migrate from a managed image to a Shared Image Gallery using the Azure CLI.
Images in an image gallery have two components, which we will create in this example:
An Image definition carries information about the image and requirements for using it. This includes whether the image is Windows or Linux, specialized or generalized, release notes, and minimum and maximum memory requirements. It is a definition of a type of image.
An image version is what is used to create a VM when using a Shared Image Gallery. You can have multiple versions of an image as needed for your environment. When you create a VM, the image version is used to create new disks for the VM. Image versions can be used multiple times.

Thank you for this video. It was useful.

Can we run sysprep on azure vm and power on and add to domain

[@PaddyMaddy26]

Hi KumariCh-de1uc, Yes, you can run sysprep on an Azure VM and then power it on and add it to a domain. Sysprep is a tool used to prepare a Windows installation for duplication, allowing you to create a customized image that can be used to deploy new virtual machines. After running sysprep on the Azure VM, you can power it on and join it to a domain just like you would with any other Windows machine. I hope this information helps. Let me know if you have any other questions. Thank you.

Feel free to comment as a new comment to get immediate response. Running Sysprep on an Azure VM is a common practice to generalize the VM before capturing it as an image. However, there are some key considerations and steps to follow: 1.Running Sysprep: You can run Sysprep on an Azure VM, but it is essential to understand that Sysprep generalizes the VM by removing system-specific data. This includes machine-specific security identifiers (SIDs), settings, and more. Once generalized, the VM will be in an out-of-box experience (OOBE) state on the next boot, requiring you to complete the setup process again. 2.Taking a Snapshot vs. Image Capture: Snapshot: A snapshot captures the state of the VM's disks at a specific point in time. While you can use a snapshot to create a new VM, it is not the same as an image. A snapshot is best used for backup or restoring a VM to a previous state. Image Capture: Capturing an image of a generalized VM creates a reusable template that can be used to deploy multiple identical VMs. This is ideal for creating standardized environments. 3. Post-Sysprep Considerations: If you Sysprep a VM and take a snapshot, you can use that snapshot to create new VMs. However, each VM created from the snapshot will be in the OOBE state and will not automatically join the domain. After creating a new VM from the snapshot, you will need to complete the OOBE process, set up the VM, and then manually join it to the domain. 4. Recommendations: If your goal is to deploy multiple VMs with a consistent configuration, it's better to capture an image of the generalized VM. This image can then be used to create new VMs that will also be in a generalized state, ready for domain joining and further configuration. If you only need to restore the state of a single VM, taking a snapshot might be sufficient. In summary, while you can use Sysprep on an Azure VM and take a snapshot, using an image is generally the preferred method for deploying multiple VMs with consistent configurations.

So you mean if we deploy a vm from the snapshot . Azure will take care of sysprep during vm creation process This kind of vm creation will it effect the running domain vm where we taken the snapshot

[@KumariCh-de1uc]

Regarding creating a new vm from existing domain joined vm using snapshot .if user need a similar kind of setup with 2vms. Instead of taking downtime of the existing vm for capturing can we go with snapshot option . 1.This vm creation process from snapshot will not effect the existing? 2.Vm deployment from snapshot azure will do sysprep during the deployment? 3. As we are creating vm from snapshot this will have new hostname and Sid right. 4. Vm Snapshot is domain joined .if we deploy the vm will it be autojoined to domained after the deployment?

[@PaddyMaddy26]

Hello KumariCh-de1uc, Thank you for your questions regarding creating a new VM from an existing domain joined VM using a snapshot. 1. Creating a new VM from a snapshot of an existing VM will not affect the existing VM. The snapshot is a point-in-time copy of the VM's disk, so any changes made to the new VM will not impact the existing VM. 2. When deploying a VM from a snapshot in Azure, it does not automatically run sysprep during the deployment process. You may need to manually run sysprep on the new VM if necessary. 3. Yes, when creating a VM from a snapshot, it will have a new hostname and a new SID (Security Identifier). 4. If the VM snapshot is domain joined, the new VM created from the snapshot should retain its domain join status. However, you may need to verify and ensure that the necessary configurations are in place for the new VM to automatically rejoin the domain after deployment. I hope this answers your questions, please let me know if you need any further clarification. Thank you.

@@PaddyMaddy26 So if we run the sysprep for azure vm. After power on normally it will ask admin password and some other default setting . But in azure we don't have the console how this will be proceed. Can you please create a video on this to have better understanding
