How to Use VMware's OVF Converter Tool:
VMware's OVF Tool (and OVF Tool User Guide) can be downloaded for free from the following location:
http://www.vmware.com/support/developer/ovf/
Install this utility on your local machine where your VM images reside.
In the following example, VMware OVF Tool 2.1 for Windows 64 bit was downloaded and installed on a Windows 7 64-bit machine to the following location:
c:\Program Files\VMware\VMware OVF Tool\
Before running OVF Tool, we would recommend ensuring that your image resides by itself in its own directory, for example:
e:\myvirtualmachines\myovf\myimage.ovf
We would then recommend creating a new (separate) directory for your converted VMX image, for example:
e:\myvirtualmachines\myvmx\
Once OVF Tool is installed and your conversion directory has been created, open a command prompt. This will be different depending on which OS your local machine is running; in Windows 7, navigate to "Start", type "cmd" in the search bar, and select "cmd.exe" when it appears in the search results.
Navigate to where OVF Tool is installed by using a command such as:
cd "c:\Program Files\VMware\VMware OVF Tool"
Run OVF Tool by using the following (or similar) command. Note that the first section of the command calls out the name and location of your current OVF file, and the second section of the command declares where the new VMX file should be placed (and what it should be called):
ovftool e:\myvirtualmachines\myovf\myimage.ovf e:\myvirtualmachines\myvmx\myimage.vmx
