I cannot start my VM. Created an image to clone from but now cannot start the source VM

William Bertolotti 0 Reputation points

I have a VM that was running fine. I wanted to clone to a 2nd VM. I created an image and tried to create the 2nd VM but that failed to deploy. I removed the 2nd VM and created manually. When I tried to start up both VMs, the new one started but the original VM failed saying it is generalized and a Start VM command wont work. All my applications and setups are on that VM and I need to recover it and be able to start it

    When you generalize a VM, you can no longer use it, only copies from it.

    Hello, @William Bertolotti !

    How do I clone a VM?

    You can make a generalized copy of a VM however generalizing a VM will remove machine specific information such as personal account and security information as mentioned by @Jackson Martins .

    Snapshots (as used in disaster recovery) create a full, read-only copy of a virtual hard disk (VHD) which you can use as a point in time backup (or a clone) of your VM. You create a snapshot, then create a managed disk from the snapshot.

    Luis Beltran has posted a great blog that covers the process with step-by-step screenshots:


    I hope this helps!
