Cloning virtual machines
Clone a Virtual Machine is the mechanism
that allows to use an existing virtual machine to create a copy of
The cloning process copies all existing disks (And the data in
them), such as CPU and memory configurations of a virtual
machine to another.
This task may take considerable time depending on the size of
the disks to copy.
Two virtual machines can not have the same IP addresses,
because of this, upon completion of the cloning process,
must assign IP addresses to the new virtual machine.
Uses of cloning
The cloning process can be useful in the following scenarios:
Perform a total backup of a virtual machine.
For this task you can also consider making a Snapshot. If you have already configured software on a virtual machine,
you can use as a template to create new virtual machines through
cloning, thus avoiding having to configure the software again on
each new virtual server.
Create a test environment without affecting existing
Clone a virtual machine
Go to the virtual machine to clone (The virtual machine must
be turned off).
Click on the
Enter the name of the new virtual machine, and click on the
The cloning process starts.
A progress indicator shows the process.
Edit cloned virtual machine
After the cloning, you must configure at least one new network
card in the new virtual machine.
It is then necessary to assign new IP addresses to the cloned
Name of the cloned virtual machine.
Number of CPUs of the cloned virtual machine, you can modify
Amount of RAM of the cloned machine, you can modify it.
Primary DNS from the original machine, you can modify
Secondary DNS from the original machine, you can modify
Add virtual hard disks.
Increase disk size.
It is currently not possible decrease
the size of an existing disk.
Delete existing disk: If you delete a disk
all data within
it they will be deleted. This task is irreversible. Add network cards. Cloned virtual machine does not have any
network card, you need to add at least one.
Click on the
button. The new virtual machine
will be available.
