Cloning a Virtual Machine with Instant Clone

Instant Clone technology can be used to create powered on virtual machines from the state of another powered on virtual machine. Cloning a Virtual Machine with Instant Clone as a result of an Instant Clone operation that is identical to the source virtual machine. You can use Instant Clone to create new virtual machines from a specific point in time. Because it ensures memory efficiency and allows for the creation of multiple virtual machines on a single host, instant cloning is ideal for large-scale application deployments.

Cloning a Virtual Machine with Instant Clone

An Instant Clone process creates a virtual machine known as a destination virtual machine. The destination virtual machine’s processor, virtual device, memory, and disk states are identical to those of the source virtual machine. During an Instant Clone operation, you can customize the virtual hardware of the destination virtual machine to avoid network conflicts. For example, you can change the virtual NICs’ MAC addresses or the destination virtual machine’s serial and parallel port configurations. The guest OS of the destination virtual machine is not customizable in vSphere 6.7.

The source virtual machine is stunned for a shorter amount of time, less than 1 second, during an Instant Clone operation. A new writable delta disk is generated for each virtual disk and a checkpoint is taken and transferred to the destination virtual machine while the source virtual machine is stunned. The destination virtual machine is then powered on using the checkpoint from the source. The source virtual machine restarts after the destination virtual machine is fully powered on.

Instant Cloned virtual machines are inventory objects in vCenter Server that are completely self-contained. Instant Cloned virtual machines can be managed in the same way as regular virtual machines.

Only the API calls in vSphere 6.7 allow you to Cloning a Virtual Machine with Instant Clone

What is a VMware instant clone, and how does it work?

VMware Instant Clone is a feature of VMware’s vSphere software that allows administrators to quickly clone a virtual machine that is already running. The VMware Instant Clone feature forks off an existing virtual machine (known as the parent VM) to create one or more child virtual machines.

Can you create instant clones with vMotion?

Storage vMotion and instant clones are both compatible. The Storage DRS cluster does not appear in the list in the desktop pool creation wizard when you create an instant-clone desktop pool on a Storage DRS datastore.

Is it possible to duplicate a virtual machine?

Users can create a clone or a snapshot of a virtual machine with VMware. A snapshot copies the virtual machine’s disk file to preserve its current state. Cloning is the only option if you need to create a new VM that will run on its own.

What is the best way to create an instant clone pool?

To Create an Instant Clone pool Access the Inventory > Select Desktops area and then click to Add. Select the Automated Desktop Pool option and click to Next. Select Instant Clone option and the vCenter then click to Next. Select Floating as user assignment option.

What is the differences between a linked and an instant clone?

The linked clone and the replica VM share virtual disks. A diff disk or redo disk stores the differential—the bits of software that are unique to the linked clone. The memory of the running parent VM from which the instant clone is created is shared at creation time.

What’s the best way to recompose an instant clone?

On the Summary tab, click Push Image, then Schedule for Instant Clones. If you’re using Composer, go to View Composer and then recompose. Select the new snapshot from the Image page. Take note of the monitor/resolution settings in the snapshot.
