How to create a VM from a snapshot in Azure

Hello All,

If you are using azure cloud in your environment so you have definitely faced issue where your VM got corrupted or due to some other issues you are unable to connect to it.

This might be production or development machine and then it creates a big issue as you have some important data on that vm disks which you have not backed up.

This issue mostly occurs when you make changes in fstab file or any boot file missing from your VM.

Sometime there might be some other issues which are related to networking. So it’s always a good idea to check your network connection and basic troubleshooting before applying this solution.

In this blog post we will go through the steps on how to create a new vm from existing vm’s disk snapshot.

I have clearly mentioned the steps to create the snapshot of existing vm and how to create a new vm from created snapshot.

Below steps will help you to create an azure vm from azure disk snapshot.

Step 1: Create a snapshot

First we have to create the snapshot of existing vm which has the issue.

select Azure virtual machine from all services and navigate to disk blade from left panel and click on create snapshot. this will give you option to create snapshot of disk.

Step 2: Fill out info

After clicking on create snapshot tab you will get a dialogue box where you have to fill the required details.

Fill up the required information like subscription name, Resource group, account type and name for the snapshot. (note down the name of snapshot as in most cases we forgot the snapshot name)

Step 3: Create a new Disk

Go to All services --> disks --> create managed disk and provide all the required details to create managed disk.

1. subscription name (use the same subscription name where your vm is created)

2. resource group (you can create a new Resource group or can use exisitng)

3. disk name (name of new disk )

4. region name (chose the same region)

5. source snapshot

6. size.

(Make sure you select the region your snapshot was saved in, otherwise your snapshot won't show.)

after providing all the details click on review and create button.

Step 4: Create a new VM from the disk

Once disk created go to disks and select create Vm option.

Step 5: Fill out the info

Once again provide all the required information as needed. after providing information deploy the vm and wait until it gets created.

after deployment completed you should have a fully working restored virtual machine.

So by this way you can create a new vm using disk snapshot.

Once the vm is created login to the vm and do the basic sanity test.

Let me know in comment section if you facing any issue while creating new vm from disk snapshot. I will try my best to help you.

Thank you!!!

Ansible

Ansible is an open-source software provisioning, configuration management, and application-deployment tool. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. It includes its own declarative language to describe system configuration. Ansible was written by Michael DeHaan and acquired by Red Hat in 2015. Ansible is agentless, temporarily connecting remotely via SSH or Windows Remote Management (allowing remote PowerShell execution) to do its tasks. Platform support Control machines have to be a Linux/Unix host (for example SUSE Linux Enterprise, Red Hat Enterprise Linux, Debian, CentOS, macOS, BSD, Ubuntu, and Python 2.7 or 3.5 is required. Managed nodes, if they are Unix-like, must have Python 2.4 or later. For managed nodes with Python 2.5 or earlier, the python-simplejson package is also required. Since version 1.7, Ansible can also manage Windows nodes. In this case, native PowerShell remoting supported by the WS-Managemen...

Kubernetes-Update

https://kubernetes.io/ Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon 15 years of experience of running production workloads at Google , combined with best-of-breed ideas and practices from the community. Latest Verion:- 1.19 Kubernetes Objects Kubernetes defines a set of building blocks ("primitives"), which collectively provide mechanisms that deploy, maintain, and scale applications based on CPU, memory or custom metrics. Kubernetes is loosely coupled and extensible to meet different workloads. This extensibility is provided in large part by the Kubernetes API, which is used by int...
