This tutorial walks through the installation of Debian Linux on VirtualBox, then the cloning and exporting of it into VMware-Workstation in a fully working condition. If you have not yet installed VirtualBox go to the quick tutorial. It also assumes that you have VMware-Workstation installed somewhere though not necessarily on the same machine. The host operating system is Centos 6 Linux.
I used a Debian disk but you should be able to use any distro.
The main thing to remember when first installing the guest OS on VirtualBox is ensure that the hard disk type chosen is the VMDK format, in case the need arises to move it.
The following shows the installation of a Debian Linux distro onto VirtualBox and then the cloning of it into VMware-Workstation.
Installing on VirtualBox
Open VirtualBox and create new virtual disk
Assign a suitable ram amount
Create a new disk
Select the VMDK format
Select fixed disk
Assign a disk size
Hit 'Create' and wait
After a few minutes your disk will be created and ready to install the operating system. I am not going to go into that here as I assume that if you are a Linux user you will know how to install an operating system whether it is on a VM or a physical drive. Just be aware that during the installation process it is probably best to select full screen mode and you may have to toggle between VM and your computer occasionally with Right Ctrl.
Below is the OS as I installed it after completing the steps described above.
Debian installed on Virtualbox
Cloning from VirtualBox
Now we are going to clone the Debian VM into a state ready to import into VMware-Workstation.
With your VM shut down but selected in the left panel, go to 'Machine' > 'Clone' remembering to check the
'reinitialise the mac address' box
Click 'Next' and at the next screen select 'Full Clone', then hit 'clone' and wait. It takes quite a while to complete, when it does you will have a clone folder in your VirtualBox VMs directory.
Now copy the clone folder to the VMware directory which should be in your home directory. Do this manually via your file manager as it can get messy in the terminal due to folder name spaces.
Once it has copied over we are ready to start the import.
Importing into VMware-Workstation
Open up VMware and start the New Virtual Machine wizard.
Select advanced options
Leave at defaults
Select install OS later
Select OS type and browse to the folder you copied earlier
Select a suitable ram amount
Select network connection
Select hard drive controller
Select use existing disc
Browse to the cloned disk and select it
Select convert to newer format
Click finish and your cloned disk is imported ready to start.
So now your new import will be showing as 'Other Linux' unless you specified a distribution, hit 'Power on this Virtual Machine'
and let it load up. You will get something resembling the image below.
You can now install VMware tools and finish any drivers etc. The above procedure can be performed on any OS you have installed, not just Linux guests.
