How to clone a VMware Server virtual machine

Here is a quick guide on how to clone a VMware Server Virtual Machine and bring it up as a new VM in its own right. This allows you to build one base line image and then produce several separate servers from it, or for example, to clone a production VM to test installing a software upgrade on it.

1. First off, you need to have built your source server
2. Now ensure it is shut down & VMware Server shows it as powered off.
3. Next copy the VM’s folder to a new folder eg: copy c:\Virtual_Machines\CentOS_5.1\ to c:\Virtual_Machines\devel-server\
4. Now we need to rename the VMware config file, change into your new VM’s directory and rename the .vmx file. eg: from centos.vmx to devel-server.vmx
5. You now need to change the name of the VM in the config file. Open the .vmx file in a text editor and edit the display name line as required. Ensure this does not clash with any of your other VMs.
eg: form this: displayName = “centos” to this: displayName = “devel-server”
6. You can also rename the disks if you need to, you will also need to change the disk names in the config file. However, I normally setup the disks myself when i create the machine as disk1 disk2 etc and when I clone the server all its disks are duplicated in the new folder, that way i don’t need to rename them and they are completely seperate servers. Nice and clean way of doing things. If your unsure leave your disk files and their entires in your config file alone.
7. Now open VMware Server Console, and connect to your server
8. Then click on File, Open, Browse and locate your new VMX config file in your new VM’s folder.
9. Now you should be able to power up your new VM.
10. You will now need to tell it to create a new UUID when asked

This also works on linux but your server VM path will be more like: /var/lib/vmware/Virtual Machines

Other things to think about, the hostname of your server, and its IP address. These are the two issues people have once they have cloned a server, if its DHCP, your ok, if its static, boot only one at a time.

The first time you boot your new system (The clone) set its hostname and IP configuration.

This week I needed to do some testing on two different server setups and did not have any spare boxes handy. I have found in the past that i have spent a lot of time getting hardware together, plugging it in and finding install CD’s.

I set about trying an easier way of testing, and having a good spec laptop which I use day to day, I decided to install VMware Server on it. Then I created a Virtual Machine and installed a clean CentOS 5.1 build on it.

I needed two systems for my testing so decided to keep this install as my “template” or “clean base” and clone it. I would then have “clean”, “server1″ and “server2″. When I finished my testing I could delete the two server VM’s and would be ready to start again next time.

It worked great and I would highly recommend it. (Plus its Free!)
