A clone is a copy of an existing virtual machine. The existing virtual machine is called the parent of the clone. If you want to save the current state of the virtual machine, so you can revert to that state in case you make a mistake, take a snapshot. If you want to make a copy of a virtual machine for separate use, create a clone. Installing a guest operating system and applications can be time consuming.

With clones, you can make many copies of a virtual machine from a single installation and configuration process. With clones you can conveniently make complete copies of a virtual machine, without browsing a host file system or worrying if you have located all the configuration files.

A full clone is an independent virtual machine, with no need to access the parent. Full clones do not require an ongoing connection to the parent virtual machine. Because a full clone does not share virtual disks with the parent virtual machine, full clones generally perform better than linked clones.

However, full clones take longer to create than linked clones.

Creating a full clone can take several minutes if the files involved are large. A linked clone is made from a snapshot of the parent. See Understanding Snapshots. All files available on the parent at the moment of the snapshot continue to remain available to the linked clone. Ongoing changes to the virtual disk of the parent do not affect the linked clone, and changes to the disk of the linked clone do not affect the parent.

A linked clone must have access to the parent. Without access to the parent, a linked clone is disabled. Linked clones are created swiftly, so you can easily create a unique virtual machine for each task you have.

You can also easily share a virtual machine with other users by storing the virtual machine on your local network, where other users can quickly make a linked clone. This facilitates collaboration: for example, a support team can reproduce a bug in a virtual machine, and an engineer can quickly make a linked clone of that virtual machine to work on the bug. A full clone is a complete and independent copy of a virtual machine.

However, the full clone duplicates only the state of the virtual machine at the instant of the cloning operation. Thus the full clone does not have access to any snapshots that may exist of the parent virtual machine. VMware Workstation 5. Changes made to a clone do not affect the parent virtual machine. Changes made to the parent virtual machine do not appear in a clone.

An MIS department can clone a virtual machine for each employee, with a suite of preconfigured office applications. A virtual machine can be configured with a complete development environment and then cloned repeatedly as a baseline configuration for software testing.

A teacher can clone a virtual machine for each student, with all the lessons and labs required for the term. A full clone is an independent copy of a virtual machine that shares nothing with the parent virtual machine after the cloning operation.Additionally, it depends on the mechanism of the VM cloning process.

Additionally, every computer in the AD domain has its own identification. This identification is not its name. The computer name is useful for us. Moreover, this identifier must be unique.

SID is calculated in the process of the installation of every Windows machine. I discovered this problem preparing an article about remote administration and NIC teaming. Even better; I found the solution for this situation. So hold your breath and keep reading. I needed at least two servers for my scenario.

I just need to make two linked clones and to save the precious disk space. My SSD drive is limited in size. I made two VMs. The first became the AD domain controller server. When I tried to add the second machine into the domain, I faced the error. The SID of the domain i. If you check this message, you will see that you have the solution right in front of you.

We need to run the tool named SysPrep. Yes, with the SysPrep tool we can delete the SID and all other settings, leaving the machine in an uninitialized state. The machine will be initialized on its first run. This mechanism allows admins to clone both physical and virtual machines easily. Our VM has days left until expiry of the evaluation license. Locate the SysPrep tool and run it as administrator.

After a while, the application window will appear on the screen. In the Core version just type the command.

The rest is the same. We want to clean all personalized settings of the machine. However, we want to return this machine to an uninitialized state, as we just installed it. Therefore, tick the checkbox named Generalize. The third option depends on your preferences. However, when you want to reset your master machine, you will need to shut it down after this process finished.

The SysPrep tool will start. The first phase is the cleanup phase, where settings will be cleared. The second phase will perform generalization re-initialization of the machine.Windows SID needs to be changed after copying a virtual machine directory. These SIDs are unique alphanumeric strings that correspond to a single object in the domain. When you copy a virtual machine directory, the resultant virtual machine has the same SID as the original virtual machine. When you try joining this new virtual machine to the same domain where the original virtual machine is, Active Directory sees two machines with a single SID and warns you that there is a SID conflict.

This is the only method that is supported by Microsoft. This table lists the Sysprep version for the Windows versions that are supported for Image Customization. Compare the Sysprep version number with the Windows version for which it is intended:.
